Turn off screenshot transition into long screenshots for rotations

If the user rotates the phone between the initial screenshot capture
and the long screenshot capture, the views will be completely
different and it doesn't make sense to try to transition from the
preview into the long screenshots activity.

This change just turns off the preview transition for this case
(though we still show the scrim and fade it out during the
transition).
