Fix ride list focus on data change

.. whenever ride data is changed, metadata, ride data etc then shortly
   after making the change the ride list would lose focus and lose
   the current selection

.. this was caused by reseetting the ride list model when data changed.
   this was unneccessary and also time consuming.

.. it took 3 hours of debugging to comment out 1 offending line, I think
   that might be a record !
