Fix gear being covered on notification update

If a notification is updated to be non clearable but is in the middle of
being dismissed then it is snapped back into place. Part of the ways to
check if it was being dismissed is by checking the translation of the
notification.

In the case that the notification was translated to display the gear, then
when it was updated it would be snapped back over the gear. This CL fixes
this issue by snapping back to the gear instead of 0 in this situation.
