* 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.
+automaticallyNotifiesObserversForKey: returns YES, and match Cocoa behavior.
