Can't re-request e2ee key from your other sessions or other people in the room

[yasinishyn]

Describe the bug When the encryption key is missing for a message you can't re-request it in your other sessions or with other people in the same encrypted room. There is nothing happening on UI and in-code behavior is not clear.

To Reproduce Steps to reproduce the behavior:

1. Login with the same user with two different devices;
2. Make sure the e2ee encryption is setup;
3. Create an encrypted room;
4. Send few messaged in this encrypted room, and verify you see the messages on both devices;
5. re-login on one of the devices and skip the verification steps.
6. Click on "Re-request encryption keys from your other sessions."

Instead of step 1, you can have two different users, and the behavior is almost the same, except that it's a bit more clear why it doesn't work. The failure is with the session key not found in src/crypto/algorithms/megolm.ts

    public async reshareKeyWithDevice(
        senderKey: string,
        sessionId: string,
        userId: string,
        device: DeviceInfo,
    ): Promise<void> {
        const obSessionInfo = this.outboundSessions[sessionId];
        console.log('AY sessionId', sessionId)
        console.log('AY obSessionInfo', obSessionInfo)
        console.log('AY this.outboundSessions', this.outboundSessions)
        if (!obSessionInfo) {
            logger.debug(`megolm session ${sessionId} not found: not re-sharing keys`);
            return;
        }
// ...

For the same user (different devices), The execution flow ends on

this.emit(CryptoEvent.RoomKeyRequest, req);

inside src/crypto/index.ts

however, there is no listener for the CryptoEvent.RoomKeyRequest event nor any other log output (error/info, etc..).

Expected behavior E2EE keys are shared or a verification flow is started, and message becomes visible on the device.
