When I restore a folder from backups, I usually restore all the message 
files, plus the cyrus.header file.  Then I run reconstruct -f on the 
mailbox.

If you don't have the cyrus.header file for user/me/test, I think you have 
2 options:

1.  Copy the cyrus.header file from the parent mailbox (user/me) and run 
reconstruct -f.

2.  Create the folder first using cyradm, then copy the message file into 
it and run reconstruct -f.
