Fix and simplify check for maximum number of favorite communities

Browse source 
Because of incorrect index/size math, two favorite communities were removed when exceeding the maximum number of three favorite communities instead of only one. The check can be simplified because the maximum number of favorite communities can never be exceeded, so at most the first element needs to be removed from the vector.

Closes #7935.
