Subject: [PATCH] Auto-connect input should not disconnect other ports

This fixes an issue with existing MIDI routing between MIDI tracks
and/or busses. Automatic MIDI connections should only dis/re-connect
ports that are explicitly configured in Preferences > MIDI Ports
and leave all other connections alone.
