Make sure the relayoutWindow is called when Activity restarted 

The host visibility was always invisible while making an Activity
window active because the host visibility was updated afterward
(in ActivityThread#handleStartActivity). Therefore, #relayoutWindow
could be skipped and not recreating Surface if the view visibility is
not changed since last traversal.
