[iOS] Event handlers are not called after hot restart

[AndriiVivcharenko]

Describe the bug Whenever I do a hot restart and then join any channel it stops handling events (joinChannelSuccess, userJoined etc). I Didn't pay much attention to this before until I got the same behavior in the release build uploaded to testflight. I don't know when exactly it happens in the release build, but it didn't work for hours and then started working again in the same build. I created an isolated example in a separate repo. Tried it with both temp token / generated access token.

To Reproduce Steps to reproduce the behavior:

1. Start the example and click the "join channel" button on two phones
2. Leave the channel on the second phone
3. Do a hot restart
4. Join the channel again and see that the first one sees joined user, but on the second phone doesn't handle events, and _joined is not true because joinChannelSuccess wasn't called.

Smartphone:

• Device: iPhone 8 Plus, iPhohe X
• OS: 15.5, 15.3.1
• Version 5.2.0

Additional context Logs from the phone where events were not called. I removed my appid and token from the iris log file agora-iris.log agorasdk.log
