Fix filtered deck being displayed in the ImageOcclusion page

If a filtered deck is selected and we go to the ImageOcclusion
page to add, the filtered deck will be displayed in the deck selector
although we can't add to a filtered deck(the actual code handles this
by adding to the 'Default' deck).

The fix consists in showing the 'Default' deck so a user is not
confused about the deck where his new card will go.
