feat(Core/Player): Allow stay in group when logged out (#10887)

* Config option

* Extra check

* Fixes

Updated some comments
Removed the config option from the first if since it's not necessary (afaik)

* REVERT

Reverting the if to what I had it at originally until I can get some input on it...

* Updated if

Got some input and this is working as intended

* Update World.cpp

* Update src/server/worldserver/worldserver.conf.dist
