handover test: add test 30: de-congest TCH/F by moving to dyn TS TCH/H 

In the test, show the undesired behavior of moving non-dynamic timeslots first,
because they are the first to be considered in the congestion resolution loop.
The behavior will be fixed in Ic221b8d2687cdec0bf94410c84a4da43853f0900.
