Hide taskbar icons when recents button is disabled

Browse Source 
The idea is that both taskbar icons and recents navigate you to new apps, which we'd want to disable in similar contexts. Hence reusing FLAG_DISABLE_RECENTS.

Test: locally set FLAG_DISABLE_RECENTS=true, ensure taskbar icons don't show up (both in 3 button mode and gesture nav)
