Summary: presence: wrong NOTIFY with "reason=timeout"

Initial Comment:
OpenSIPS trunk rev 5694.

I'm experimienting some issues in NOTIFY's from presence server module. "Sometimes" (but really often) when a refresh PUBLISH arrives (matching "SIP-If-Match") presence module generates a NOTIFY with:
  Subscription-State: terminated;reason=timeout

This forces the client to terminate the current subscription dialogs and resend a new initial SUBSCRIBE. Unfortunatelly some clients (as Qutecom) seem to react wrongly when this issue. Anyhow, I think there is some bug in the presence module behaviour.

I attach a SIP trave very simple:

- Just one user 30000 at domain.org.
- It publishes its state and subscribes to its state.

Note how the NOTIFY in line 428 has a strange header value:
  Subscription-State: terminated;reason=timeout
After it, Twinkle (which recats well on it) generates a new out-of-dialog SUBSCRIBE. But if Qutecom is being used, it doesn't generate the SUBSCRIBE (probably a bug inQutecom) and the subscription dissapear from "active_watchers" table.
