[hotfix] fix mia on server-sent stop (#284)

Hotfix for now, but the whole extract+quit out logic will need to be
simplified/unified in the next major release.

Sequence of events triggering the bug:
- guest extracts (regardless of exfil type/map)
- guest's collider is disabled so that existing players do not get
bodyblocked
- no more collision with exfil point means `OnCancelExtraction` is
called, which has new "runner" detection logic, setting the exit status
to mia (restoring "default" value)
- host quits (i.e. pressed F8)
- host's `profileId` is before guest's `profileId` in the `Players` list
- host "kicks" all players including itself before it "kicks" the guest
- nodejs server sees host left, sends a "everybody leave now!" message
to all remaining connected players, including guest
- guest leaves without recomputing its exit status, which was set to MIA
by `OnCancelExtraction` above
- player sad
