subrepo: propagate non-default path on outgoing
There was already a fix made in 5dbff89cf107 for pull and push commands. I did
the same for the outgoing command.
The problem I identified is that when the parent repository has multiple paths,
the outgoing command was not respecting the parent path used and was always
using the default path for subrepositories.
