Regbot persistent call-id and other fixes (#130)

* use gw sid as call id and fix bug on updateing regbots

we must not mutate gw directly, as it is cached in the gateways array
 and adding properties would cause the JSON.stringify comparison to detect a
 false change on every checkStatus cycle, triggering unnecessary re-registrations.

* fix tests

add influx and also the registered now changes to remove previous reg on update

* better test scenario

still checks that we have 1 registered as expires now at 600s so it doesn't expire before the 65sec delay
