[Work] Fix work apps showing in personal tab

The problem here is that we are tracking hasWorkApps and usingTabs using the same value.
 This leads to work/personal apps showing together when clearing search since mUsingTabs is overridden to false on setLastSearchQuery and later used to determine if tabs should show.
