Fix clamodel init() with default + cleanup

Fixes #1307 
TODO: decide what to do with `sensorParams` -- make it required, or provide working default value.
If you're just checking that calling `TP()` doesn't throw an error, aren't there other tests that instatiate `TP()` in the same way? There must be. If so, you should just remove this test. 

Now, if you are truly testing some initialization process, you should have some assertions on the `TP` instance that properties were set up properly or that some side affect was executed.
