Fix CTL title not showing sometimes

Happens when the collapsed bounds overlap the expanded
bounds. That normally doesn't happen, but it can happen
when the the CTL is sufficiently small.

Fixed by allowing the expanded bounds to cover the whole
CollapsingToolbarLayout. Which is what developers would
expect anyway when setting the gravity.
