fix(kicked): leave the conference immediately

There is no reason to wait for for the event to be emitted.

JitsiConference.js

     const actorParticipant = this.participants.get(actorId);
 
     if (isSelfPresence) {
+        this.leave().finally(() => this.xmpp.disconnect());
         this.eventEmitter.emit(
             JitsiConferenceEvents.KICKED, actorParticipant, reason, isReplaceParticipant);
 
-        this.leave().finally(() => this.xmpp.disconnect());
-
         return;
     }
