media_sideload_image() doesn't handle dynamic image url's well

As a result, the preg_match() for the file extension fails and issues a notice (no file extension in that url, although the redirection location does have).
The handling of a download failure also seems hairy, upon failure, it still attempts further importing before loading - I haven't looked into that too far.
