extends -> file used more than once does not work in podman-compose correctly for 2nd and next services

[diodakus]

Describe the bug
When docker-compose.yml use extends tag what loads config by file tag from docker-compose-general.yml file for first service from docker-compose.yml - sh works well, but for second ci-dev-sh not. It means that incorrectly recognize docker image for second service - ci-dev-sh and does not inherit mounts from sh.

To Reproduce
Steps to reproduce the behavior:

1. create docker-compose.yml file with content:

version: '3.5'
services:
  sh:
    extends:
      file: docker-compose-general.yml
      service: sh2

  ci-dev-sh:
    extends:
      file: docker-compose-general.yml
      service: ci-dev-sh2

2. create docker-compose-general.yml file with content:

services:
  sh2:
    command: [/bin/sh]
    image: busybox
    volumes:
      - /tmp/service_sh:/tmp/service_sh:rw

  ci-dev-sh2:
    extends:
      service: sh2
    volumes:
      - /tmp/service_ci-dev-sh:/tmp/service_ci-dev-sh:rw

3. run 1st command: podman-compose run --rm sh sh
4. run 2nd command: podman-compose run --rm ci-dev-sh sh

1st command works as expected - started sh service:
podman run --name=slawek_sh_tmp50285 --rm -i --pod=pod_slawek --label io.podman.compose.config-hash=ff28310f0c2bb389c418e1a834ea9801adacc3f014ac99dabed617361ca2278f --label io.podman.compose.project=slawek --label io.podman.compose.version=1.0.4 --label com.docker.compose.project=slawek --label com.docker.compose.project.working_dir=/home/slawek --label com.docker.compose.project.config_files=docker-compose.yml --label com.docker.compose.container-number=1 --label com.docker.compose.service=sh -v /tmp/service_sh:/tmp/service_sh:rw --net slawek_default --network-alias sh --tty busybox sh

Expected behavior for 2nd command
podman run --name=slawek_ci-dev-sh_tmp43794 --rm -i --pod=pod_slawek --label io.podman.compose.config-hash=ff28310f0c2bb389c418e1a834ea9801adacc3f014ac99dabed617361ca2278f --label io.podman.compose.project=slawek --label io.podman.compose.version=1.0.4 --label com.docker.compose.project=slawek --label com.docker.compose.project.working_dir=/home/slawek --label com.docker.compose.project.config_files=docker-compose.yml --label com.docker.compose.container-number=1 --label com.docker.compose.service=ci-dev-sh -v /tmp/service_sh:/tmp/service_sh:rw -v /tmp/service_ci-dev-sh:/tmp/service_ci-dev-sh:rw --net slawek_default --network-alias ci-dev-sh --tty busybox sh

1. Expected docker image busybox.
2. Expected mount inherited from sh service: -v /tmp/service_sh:/tmp/service_sh:rw.

Actual behavior for 2nd command
podman run --name=slawek_ci-dev-sh_tmp43794 --rm -i --pod=pod_slawek --label io.podman.compose.config-hash=ff28310f0c2bb389c418e1a834ea9801adacc3f014ac99dabed617361ca2278f --label io.podman.compose.project=slawek --label io.podman.compose.version=1.0.4 --label com.docker.compose.project=slawek --label com.docker.compose.project.working_dir=/home/slawek --label com.docker.compose.project.config_files=docker-compose.yml --label com.docker.compose.container-number=1 --label com.docker.compose.service=ci-dev-sh -v /tmp/service_ci-dev-sh:/tmp/service_ci-dev-sh:rw --net slawek_default --network-alias ci-dev-sh --tty slawek_ci-dev-sh sh

1. Bad docker image. Is: slawek_ci-dev-sh, should be: busybox
2. Missing mount -v /tmp/service_sh:/tmp/service_sh:rw - looks like not inherited from service sh.

As you can see podman-compose is still picking up the old folder /var/mnt/shared/apps/docker/qbittorrent/config which is removed by now. The OS was restarted as well prior to this command execution.
It's almost like the previous versions of the config were appended.
