[mod_callcenter] FS-9347: Do not log as error when the member is gone just before we assigned an agent, now logging as DEBUG

[mod_callcenter] FS-9723: Fixing cc_warning_tone, using switch_ivr_play_file instead of queue private event

When someone set any wss server and do login
VC doesn't record the settings on localStorage,
so when we reload the browser, it will try to connect on
"wss://" + window.location.hostname + ":8082" and if
this wss server is offline for any reason, user will
be stuck on splash screen by auto-login step plus reconnect
modal blocking any action.

- Added button "Change Server" on modal reconnection alert;
- Stop jsonRpcClient retry timeout and delete verto instance
to create a new one when user login with new wss server;
- Record wss server and hostname on localStorage.
