Restoring previous conditions in setfollowplayer().
Current conditions appeared with commit: https://github.com/assaultcube/AC/commit/8f39911eb0725b22bb4dc3a50d3e89702afcc49c
The problem with its is, that when player is SPECTATOR,  then "/setfollowplayer CN" command works only on players in CLA team, and should work on all, like "changefollowplayer".
This commit fixes that. Thread related to this bug: http://forum.cubers.net/thread-7495.html
