REVISION SUMMARY
  After creating a new snippet with an assigned keyboard shortcut, this shortcut did not work directly. This was because the snippet QActions are added to a widget by a rowsInserted() signal, but the new snippet's QAction did not exist yet at this time. This change ensures that the new snippet's QAction is created in time.

TEST PLAN
  I tested it manually.
