tests: fix TestHandlerHandlePart tests

these tests were previously passing, but doing so erroneously.
I believe that an update to mock caused them to start failing.

I've updated the tests now.  The simple change is
replacing 'assert_called_with_once' with 'assert_called_once_with'.

The second set of changes is seemingly a correction of the following tests
expectations:
 test_normal_version_2 : was not expecting to get frequency passed into
    handle_part, but should have been.
 test_no_handle_when_modfreq_once: was expecting to have handle_part
    called even though the test implies otherwise.
 test_exception_is_caught: this test just looked broken.
    Now, we're testing that the part handler is called and that no
    exception is raised past handle_part
