Dive list: invert default sort order for sort by date / number

Browse source 
Commit 6dc1d239f8 introduced a
well-defined sort order in the case of equal contents. It changed
the code for sorting by date to simply use the order of the
source model.

BUT: The source-model was already sorted in descending order
on date. Thus setting the default order on descening by date,
the data was then presented as *ascending* by date.

Change this back to descending by always using default-ascending
in the filter model.

Ultimately, the source model should simply reflect the ordering
of the core-data (ascending on date), but such a change is
too invasive shortly before release.
