Fix Resource.__eq__ mismatch semantics of object equal
The __eq__ of apiclient.base.Resource will return True, if the two objects have same id, even if they have different other attributes value. The behavior is weird and don't match the semantics of object equal. The objects that have different value should be different objects. Fix this issue and add some test cases in this patch.
