Subject: Oops. Don't do "FETCH 1:0" when the folder is empty.

	* providers/imap/camel-imap-folder.c (imap_refresh_info): Oops.
	Don't do "FETCH 1:0" when the folder is empty.
	(imap_protocol_get_summary_specifier): Request RFC822.SIZE too.
	(imap_update_summary): Parse RFC822.SIZE and add it to the
	summary.
