Cleanup: Remove MultiFilterSortModel::model

The source-model was cached in MultiFilterSortModel. For simplicity,
remove that and simply access via DiveTripModel::instance(). There
is only one instance where the cached model was used: when comparing
items for sorting. Thus, in indirection is added in a "hot" path.
Nevertheless, this will dwarf against the cost of string comparison.
