Image Capture Android: only restore preview parameters after photo is taken

Image Capture Android: only restore preview parameters after photo is taken

This CL introduces a member variable |mPreviewParameters| to
cache the preview capture parameters in order to restore them
after a picture is being taken and, more importantly (see bug),
delays restoring those parameters until after the picture is
actually taken.

While debugging these changes with a Nexus 7 and a Galaxy Note 2
7100, I reckoned that the Nexus 7 is very delicate so I added
some try-catches and avoided setting the picture resolution
if not truly set by the user (== use preview size).
