This part of the code had that horrible pattern, where reseting the model would invalidate all pointers to the DiveTrip model. Internalize these complexities in the MultiFilterSortModel. All accesses are now performed via that proxy model. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
