master: Don't crash if peer reconnects before we activate it

Browse Source 
`activate_peer` does little more than wiring up some txwatches and
asking `gossipd` to reconnect to the peer. If the peer manages to
reconnect before we activate then we would crash.

This just changes the `assert` causing the crash into a conditional
whether we need to reconnect or not.
