Fix Offline IM E-Mails Not Being Sent

Users account object was not returned in offline IM module because UUID
was passed as a string causing the find account method to treat it as a
User Name. Also prevent E-Mail module including headers for prim
information when used for IMs.
Stop WebUtils spamming console with JSON data

Grid server trying to connect to offline regions will fill logs up with
the full decoded JSON data it was trying to send. Warning still shown
just prevent the HUGE string of data being appended to the end. Thing
this was for debugging but no longer needed?
