QPauseAnimation: extend tests and fix binding loop

Browse Source 
Extend the unit-tests for bindable properties and fix the discovered
binding loop by using {set}ValueBypassingBindings() in the setter of
the duration property.

The code refactoring does not modify the setter logic, because
previously the binding was anyway implicitly removed when calling the
assignment operator. The updated code just does it explicitly.

Task-number: QTBUG-116346
Pick-to: 6.6 6.5
