The bridged messages (Discord) either should not be backed up or should have actual data.

The easiest solution is just to remove them. We'll see if we want to support them later

Steps to reproduce

0. Have a community with bridged messages (eg Status)
1. Backup with messages
2. Import backup

Expected behavior

No bridged messages

Actual behavior

Empty bridged messages
