def ==(other)

This is an unfortunate side effect from ActiveRecord, but this should be safe unless the RHS redefines == in a nonsensical manner
By making the other object run the comparison, we're sure the call gets delegated to the proxy target
such as ActiveRecords belongs_to proxy objects
This allows for comparing the mock to other objects that proxy 
def ==(other)
  other == __mock_proxy
