BUG FIX+ GUI - Java spinner now removes members that are no more in native network map

-- spinner removes members that are no longer in the native networkmap
BUG FIX:
instead of using instance count to remove members, when member is
removed from network map we check if its elsewhere in network map and if
not we remove it from allmemberslist too

!!! TODO !!
Remove instance_count

!!! stable !!!!
