[sr-dev] default config: do loose_route() for in-dialog NOTIFY as per new RFC 6665

[Iñaki Baz Castillo]

Hi, the new RFC 6665 mandates that the subscription dialog is made
*after* the first NOTIFY from the UAS (rather than after the 200 to
the initial SUBSCRIBE). This means that the UAC MUST take the route
set from the *first* received NOTIFY (instead of taking it from the
200 to the initial SUBSCRIBE).

Therefore a proxy compliant with RFC 6665 MUST always add RR to
in-dialog NOTIFY requests and thus, I propose that the default SR
script file implements it.

Regards.
