Update -[NSMutableArray removeLastObject] (#433)

Browse source 
* Update `-[NSMutableArray removeLastObject]`

Updates the following implementation to avoid raising an exception if the array is already empty (or notifying observers if applicable):
 * `-[NSMutableArray removeLastObject]`
 * `-[GSMutableArray removeLastObject]`
 * `-[NSKeyValueMutableArray removeLastObject]`
 * `-[NSKeyValueIvarMutableArray removeLastObject]`

This brings the behavior of `-[NSMutableArray removeLastObject]` inline with the Apple implementation, improving compatibility for code bases which use both GNUStep and Apple objc/Foundation implementations.

* Add `-[NSMutableArray removeLastObject]` test case

Adds a test case to ensure `-[NSMutableArray removeLastObject]` does not raise an exception when called on an empty array.
