Silence ECONNRESET on stop

[hasezoey]

It seems like on .stop after the shutdown command it may be possible that a ECONNRESET Error happens instead of the connection being closed, similar to the already ignored connection 1 to 127.0.0.1:41485 closed message pre mongodb 4.2.

This has been originally reported on discord, where the user notes that this might only happen on replset members, but not single instances.

Example Error:

Error: read ECONNRESET
        at TCP.onStreamRead (node:internal/stream_base_commons:216:20) {
      errno: -4077,
      code: 'ECONNRESET',
      syscall: 'read'
    }
