base: Check for homeAsUp status when collapse actionbar widget

mHomeLayout should be visible if one of DISPLAY_SHOW_HOME or DISPLAY_HOME_AS_UP are set.
collapseItemActionView only checks for DISPLAY_SHOW_HOME, so applications that only uses
DISPLAY_HOME_AS_UP and uses an expandable/collapsible widget (like SearchView) doesn't
properly restore the home layout.
One sample of this behaviour is the DeskClock app. The CitiesActivity doesn't show the homeasup
indicator after collapse the searchview.
