Modifies wear Permission title height to avoid clipping

We were explicitly setting the height of the permission
screen title, which wasn't 100% guaranteed to work in all
languages. This change sets minHeight (to maintain
UI consistency) instead, and changes the height to
wrap_content to enable it to expand further if necessary.
