pua_dialoginfo: do not blindly load all dialogs
 - only dialogs with "dlg_peer" vals should be registered for callbacks
For db_extra & db_extra_bye params, create dummy SIP message in case we have NULL msg, in order to allow the evaluation of PVARs that don't actually need the SIP msg ( eg. $DLG_end_reason )
