Comment (by jnylen0):

 Tests should not affect the global state for other tests, so we reset the
 registered meta keys after each test.

 A better way to do this might be to save the registered meta keys in
 `setUp` before each test runs, and then restore them in `tearDown`.

 In the meantime you'll need to arrange for your meta keys to be registered
 at the beginning of your tests, for example in the `setUp` method of any
 relevant test classes.
