[SR-Users] BYE is being sent using the Dialog ID (did)

Even if the dialog is matched, kamailio does not automatically updates
r-uri, so dialog stored data is not used for routing, it is kept for
ability to generate BYE by itself (and send keepalives).

There is a function that can be used to update r-uri using dialog stored
data:

  *
https://www.kamailio.org/docs/modules/stable/modules/dialog.html#dialog.f.dlg_set_ruri

But it has to be explicitly used in config.

If you don't use it, then it's either something wrong in the BYE
Route/r-uri or other operations done in config.

Cheers,
Daniel
