Subject: [PATCH] Force enable vertical scrolling on profile tab change

This fixes an edge case where after performing
a variety of gestures vertical scrolling ends
up disabled. That's because at some point
the old tab's vertical scrolling is disabled
and the new tab's is enabled.

Fixes: 160086572
Test: manually played with scrolling and swiping
Test: atest ChoserActivityTest
Test: atest ResolverActivityTest
