Highlight work tab when user already in All Apps after creating WP.

When a user created a work profile and was already in the All Apps
view, the work tab was not highlighted, because the logic for that
was only in AllAppsContainerView#onScrollUpEnd(). This CL
highlights the tab when the user has resumed and the All Apps view
is expanded.
