Update the toggle state in constructor.

Before this cl, the update of toggle depends on BroadcastReceiver.
However it is not called when toggle is inited, which make the toggle in
broken state sometimes.

This cl make it execute the update method in constructor, so toggle can
get the correct state when it is created.
