modules/ims_charging: use cscf_get_public_identity_from_requri instead of msg->first_line.u.request.uri in mod.c and ims_charging.c When getting public identity from Req URI use ims_getters method instead of reading directly from message This allows ims_charging to identify subscribers to charge even when clients add extra info (e.g. phone context) after the identity in the request URI
