Runtime error when E2EE is enabled

Description

Runtime error when E2E is enabled due to rejection in _sendSessionInit (Tried to send session-init to ${pId} but we already have a session, here: https://github.com/internxt/lib-jitsi-meet/blob/master/modules/e2ee/OlmAdapter.js#L987)

Current behavior

Expected Behavior

---

OLM channels are established without problems

Possible Solution

---

It is a problem in the call logic.
When E2EE is enabled, then this chain of events happens:

• JitsiConference.prototype.toggleE2EE calls _e2eEncryption.setEnabled
• _e2eEncryption.setEnabled calls _keyHandler.setEnabled
• _keyHandler.setEnabled calls _setEnabled and setLocalParticipantProperty (here the issue starts)
• _setEnabled (in ManagedKeyHandler.js) calls _olmAdapter.initSessions(), which sends _sendSessionInit to all participants with bigger IDs
• setLocalParticipantProperty triggers SetProperty, which starts _onParticipantPropertyChanged that sends _sendSessionInit to all participants with bigger IDs AGAIN.
• Upon a second call to _sendSessionInit the rejection is triggered:

if (olmData.session) {
            logger.warn(`Tried to send session-init to ${pId} but we already have a session`);

            return Promise.reject();
 }

Steps to reproduce

---

Start a conference between 3 participants on localhost via Visual Studio Code and enable E2EE. Runtime error follows.
