[Shotwell] Dragging photos into event view

[Peter DO Smith]

If I drag an unregistered photo (from nautilus) into an event view
(after having clicked on a given event) the photo imports but I am
thrown back into the general photo view and the photo has disappeared
somewhere into the photo library.

This is somewhat counter-intuitive as I would expect to remain in that
event view and to see the photo appear in that event. After all I can
drag photos from one event into another event (very nice feature by
the way)
