Hide review UI on resume in Camera2.

Hide review UI on resume in Camera2.

PhotoModule is used for capturing intents only on legacy hardware,
and it would show broken UI when paused, then resumed during image
review (confirmation UI).

This CL fixes it by hiding the review UI on resume. This is not ideal,
but it's the same behavior as on non-legacy hardware, and the fix
was straightforward.

Test: Confirmed manually that minimizing and restoring on ARC++
      during image review discards the taken picture.
