ServerInviteDialog::handle_bye uses wrong TerminatedReason (UacBye instead of UasBye)

[FedorKiselev76]

In ServerInviteDialog::handle_bye() the dialog is terminated with
TerminatedReason::UacBye, but this code runs on the server/UAS side
handling an incoming BYE request.

async fn handle_bye(&mut self, tx: &mut Transaction) -> Result<()> {
    info!(id = %self.id(), "received bye {}", tx.original.uri);
    self.inner
        .transition(DialogState::Terminated(self.id(), TerminatedReason::UacBye))?;
    tx.reply(rsip::StatusCode::OK).await?;
    Ok(())
}


Proposed fix
self.inner.transition(
    DialogState::Terminated(self.id(), TerminatedReason::UasBye)
)?;

You can check ClientInviteDialog::handle_bye(), which uses UasBye.
While this might seem a little confusing, it works as expected.
It is designed to handle BYE requests originating from the UAS/UAC.
