Restore logistic group filters when the group is missing or empty (#1097)

* Restore logistic group filters when the group is missing or empty

Named personal logistic groups were restored by name only, so a force
without a group of that name got an empty one, and the empty filters were
uploaded again on leave. Keep assigning the name only when the force's group
already has filters, otherwise also write the stored filters.

* Restore ghost player force before logistic slots

A player waiting to respawn had its personal logistic slots restored
before its force was set. The group lookup and the filter write then
used the force the player had on this server, which could write the
incoming requests into a group shared with other players.
