FIX: CBA_fnc_deleteEntity looping over network and kill dedicated ser…

…ver (#940)

* FIX: particular case when groupowner return 0

- when a unit is created inside a group, the group locality isn't immediately the same as the unit. It is 0 which mean the `remoteExecCall`  to every client the execution of `CBA_fnc_deleteEntity`. So because the unit is only local  to server or one client, all others clients will `remeteExecCall` again the `CBA_fnc_deleteEntity`. So a remote execution is starting.
To prevent that the `CBA_fnc_deleteEntity` execution is waiting until the groupOwner is correct (not 0)

* No timeout is necessary since groupowner is always switching to a server/client

* quit waitUntil should group be deleted by other means
