Added more logging around failures in overview connecting to launcher

Added onBindingDied, onNullBinding and logging if the user has not been
setup or if launcher component is disabled. Also added a defered
callback to reconnect after a couple of seconds even if binder says its
bound but has the possiblity of the service not connected.
