Clean up some improper usage of CamelExceptions (looking at

2002-07-16  Peter Williams  <peterw@ximian.com>

	* providers/imap/camel-imap-folder.c (imap_sync_online): Clean
	up some improper usage of CamelExceptions (looking at
	camel_exception_is_set when ex = NULL).

	* providers/imap/camel-imap-store.c (get_folder_online): Here too.

	* providers/imap/camel-imap-message-cache.c
	(camel_imap_message_cache_new): Nothing sets the exception so
	don't bother to check it at the end of this function. Prevents
	a warning about checking a NULL exception's value.
