Fix unnecessary exception use in Map::getSectorXXX (#8792)

Browse Source 
The Map::getSectorNoGenerate throws an exception but no other
code is really dependent on that. Fix the odd instance of
misuse in ClientMap::emergeSector and remove the exception
throwing version of the method along with the "NoEx" suffixes
in the names of these methods.
