Add missing megolm algorithm field that was causing
the "unknown algorithm" error.

Otherwise after a restart the old account will be loaded and we
won't be able to decrypt messages from devices using the new one-time keys.

Also new one-time key upload requests will fail due to conflicts with
the existing keys with the same keyid.

- Patch the olm repo with a CMakeLists.txt file

Add more logging during message sending
