Fix a bug in previous commit: don't check for deleted messages if there

	* providers/imap/camel-imap-folder.c (camel_imap_folder_selected):
	Fix a bug in previous commit: don't check for deleted messages if
	there are no known messages in the folder (because it would end up
	sending "FETCH 0 ...").
