Fix enterAlways|enterAlwaysCollapsed with window insets

Currently we take the window inset into account twice.
This CL fixes it by only taking it into account once.

Also updated the relevant test to use a translucent
status, and thus catch this on Lollipop+. It's how
99% of apps will use this anyway.
