Claudiu Popa 0073c7b86b Fix the names of assert methods belonging to a mock
Due to mock.Mock's nature, using an undefined method will not result
in an AttributeError, since the object will be created silently. This
changed in Python 3.5, where accessing a member which doesn't exist
will raise an AttributeError explicitly. This uncovered a couple of bugs
in the test suite.
