#633 Creating new card with data wizard does not refresh number of cards in cat view

[Christa Runge]

The following issue was seen at r3940 while testing on simulator.
Scenario:

• open a database that was created with wizard and see list of its categories
• press Wizard button and add cards
• press 'Done'

Expected behavior: The new created cards are reflected in the number of cards per category
Observed behaviour: The number of cards per category is unchanged.
After selecting a category and returning to the list of categories the number of cards is correct now.
