Watcher: Clean up email server (elastic/elasticsearch#4163) 

* Do not try bind to port range but use free ephemeral port
* Start a new email server in all tests, do not use static one
* Remove selection of username/password, as it was static anyway
* Remove Listener.Handle class, as it is not needed, when not running in static context
