There are multiple reason for this. We don't uninstall the binding interface from the controller handle and we don't reset the handle pointers either. So let's uninstall all the protocols properly and reset the handles to NULL on setup().
While at it add a forgotten check when uninstalling protocols from the handle_controller and make sure the number of child controllers is 0

We should probably try for each test if it can be repeated.

Could this easily be moved to teardown()?
