Updated translucent in Pip activity test case to cover real failure case.

Changed ActivityManagerVisibleBehindActivityTests#testTranslucentActivityOnTopOfPinnedStack
test case to cover a real life failure case we were seeing on Android TV where
the top translucent activity needs to be launched into the pinned stack vs.
being moved there after launch.
