[SR-Users] Dialog module isn't decreasing the profile size, and isn't entering on event routes

[Daniel-Constantin Mierla]

Hello,

should work without dlg_manage() for bye, but it depends on dialog
matching mode and if did parameter is mirrored back in Route header. If
you can't trust the client or are not sure about dlg matching mode, it
is better to call dlg_manage() for BYE.

Cheers,
Daniel
