After upgrading server key, the client is unable to receive (silently) and send messages until relogging-in

**Describe the bug**
After upgrading server key, the client is unable to receive any message silently, and when sending messages, the messages stay gray and I won't know it can't succeed until I tap the message.

**To Reproduce**
Steps to reproduce the behavior:
1. Log in.
2. Upgrade server (synapse) key (using let's encrypt), and restart synapse.
3. Open the android client.

**Expected behavior**
The client should either work properly, or if the new key has an issue, it should pop up and ask about the new key.
