Fix to snap notification view back when not clearable while updating

When a notification is being removed by swiping action,
actual removing will be performed after the swiping animation ends.
And also, it is same when removing notifications with <Clear all> button.
The actual removing will be performed after collapsing of status bar.
But before actual removing, the notification flags can be updated
to not clearable, and then the notification view can be remain
out of display by X-translation animation.

Therefore, fix to snap the notification view back when updating
if it is not clearable and need to be come back.
