* squash(visitors): Makes sure we first disconnect before attempting a reconnect.

If the reconnect happens too quickly, before being disconnected and the conference is still not live we will detect that we are still connected and will skip connecting to visitors service, and in the next moment we will disconnect.

* squash(visitors): Slow down successful reconnects.

If a meeting was just live but was destroyed jicofo will return it is not live, but service will return that it just got live. Slows down reconnects and at some point the service will return that the meeting is not live. The drawback is that it will take some time to connect when the meeting is created and back live.

* squash(visitors): Randomize the delay up to the available value.
