Stats for D2L logins are missing sessionid in most cases

The lines below that begin with comma (,) (after the line number) are missing the sessionid. This doesn't affect the counts in the stats, but it does affect the concurrent usage graphs. All the stats with missing sessionids are being treated as if they are the same user.
