imap: fix error with empty flag updates
Fix the following error occurring when fetching new headers after IDLE:
panic: runtime error: invalid memory address or nil pointer dereference

Some IMAP messages only contain flag updates, ignore them.
Reuse the same logic than handleFetchMessageBodyPart() and
handleFechFullMessages().
