[REFACTOR] removeFromMapAndDataStore can operate on Collections

Browse Source 
Minor performance overhead for constructing MapEntry and Collections
of one element, but keeps the code cleaner and all removes can still
use the same logic to remove from map, delete from data store, signal
listeners, etc.

The MapEntry type is used instead of Pair since it will require less
operations when this is eventually used in the removeExpiredEntries path.
