mobile: fix filter flag when editing dives

Browse source 
When editing dives, the undo-command sends a filte changed signal.
The models catch the signal and check whether the filter status
changed.

The mobile-version of the dive-edit command simply exchanged the
dives. This could lead to inconsistencies when the filter flag
was overwritten. Therefore, make sure that the filter flag
is not overwritten by the dive-exchange.
