Use unique name instead of object itself when comparing between metadata elements.

Found a very subtle problem with Mondrian's DelegatingRole, that when it wraps RolapMember instance into RolapHierarchy$LimitedRollupMember, they no longer return true when equals() method is invoked with the other as an argument, which could make various parts of Pivot4J not functioning properly.

So, it would be safe to compare between unique name properties of members instead of the member objects themselves to prevent such a problem.

I'll change the relevant code to be as defensive as possible. Though it's not viable to change all the cases like checking for .contains() on List of members without making codebase a mess, so the full resolution would be possible when below issue is addressed from Mondrian project:
