[Bug]: Unable to move mail from group inbox to personal inbox

[Kabelkrant]

Description

Bulwark displays an error when moving mail from a group inbox to a personal inbox.

"Failed to move emails: Error: Failed to move email: Source email has no raw blob to copy"

The other way around, moving from a personal inbox to a group inbox works just fine. Tested with multiple emails, both plain text and HTML. This is in both the 'pro' and regular Bulwark interface.

Please see attached screen recording.

Steps to Reproduce

1. Select a message in a group inbox
2. Drag and drop the message to your personal inbox

Expected Behavior

3. The message should be moved to the new folder.

Actual Behavior

3. Bulwark displays an error and the message is not moved.
