Ensure that setVisibility is the

first operation that is done when isShowing state is collected. Before,
visibility is set to VISIBLE after view is inflated. I think there is a
race condition happening here where when isShowing is set to false,
visible is set to INVISIBLE before view inflation has completed and then
view is set to VISIBLE.

Test: I was able to reproduce the bug by longpressing the lock icon and
tapping the arrow icon in the notifications at the same time. The
unscrimmed bouncer would show ~1/60 times. After the change, I can no
longer repro.
