+++ This bug was initially created as a clone of Bug #1498532 +++ STR: Create folder under INBOX, move a message into it. Delete folder, confirm deletion. Expected behaviour: Folder should be moved to Trash and switched to not sync for offline use. All files should be removed apart from the MSF in INBOX.sbd/Trash.sbd. Actual behaviour: This mostly matches the expected behaviour, however, watching the file system with a tool, the MSF sometimes springs back to life in the original location, INBOX.sbd.
