Crash on select using multiple indexes, group by and ranker = none

[ergnuor]

Describe the environment

Manticore Search version (top line in output of bin/searchd -v or bin/indexer -v):
Manticore 3.3.0 01fc8ad@200204 release

OS version (uname -a if on a Unix-like system):
Linux debian 4.19.0-8-amd64 #1 SMP Debian 4.19.98-1 (2020-01-26) x86_64 GNU/Linux

Build version:
manticore_3.3.0-200204-01fc8ad1-release.buster_amd64-bin.deb

Describe the problem:
searchd crashes under the following conditions:

1. the search is performed using multiple indexes or a distributed index
2. GROUP BY is used
3. OPTION ranker = none is used

Steps to reproduce:

Query examples:

SELECT type_id FROM src_dist GROUP BY type_id OPTION ranker = none;    
SELECT type_id FROM src_1, src_2 GROUP BY type_id OPTION ranker = none;

I also noticed that the ranker option appears twice in the query log. Maybe this is related to the bug somehow.
