Contact sync needs to happen when we discover a new gateway

Since that can change the outcome of the sync operation.

Skip contact sync work if there are no gateways configured

Or if syncing before gateways have been discovered, etc.  Don't do the work if
we know nothing will come of it.

Call setActive anyway in CONNECTED state

There is no code that guarantees the state must go through CONNECTING
before being CONNECTED. To avoid potential bugs, call setActive anyway
here.

Add @RequiresApi annotation for dialer integration
