Fix candidate window initialization.

OnConnected/OnDisconnected observer callback is not meaning anything on
chromeos=1 build, so it calles automatically at the begging of input method
initialization.
However it is too early for CandidateWindowController to do initialization in
OnConnected, so do initialization immediately if it is available.
