ENH: Increase coverage for miscellaneous classes

Increase coverage for miscellaneous classes:
- Exercise basic object methods using the
  `ITK_EXERCISE_BASIC_OBJECT_METHODS` macro.
- Test the boolean ivars using the `ITK_TEST_SET_GET_BOOLEAN` macro.
- Use other testing macros as necessary to check for expected values.
- Test the exceptions using the `ITK_TRY_EXPECT_EXCEPTION`.
- Explicitly call the `Print` method when some ivars (e.g. containers of
  some kind) need to have some data so that the corresponding
  serialization statements in the `PrintSelf` method can be called. Call
  these methods once the instance data has been set and the filter has
  been updated.
