    IMAPX: Handle BODY[HEADER] in FETCH response.
    
    A broken IMAP server (whatever they use at Masaryk University) was
    seen having this conversation:
    
      C: A001 UID FETCH 1:* (RFC822.SIZE RFC822.HEADER FLAGS)
      S: * 1 FETCH (RFC822.SIZE 4220 BODY[HEADER] {523} ...)
      ...
    
    This confuses Camel into thinking it was a request for a full message
    and it in turn fails to update the folder summary and issues a warning
    about not being able to locate an appropriate FETCH job.
    
    This works around the issue by treating BODY[HEADER] as equivalent to
    RFC822.HEADER in untagged FETCH responses.
    
    (cherry picked from commit 7b0b0de99a2943838b08560f11d7fdf5dac7d422)
