[Serusers] record_route() & record_route_preset() di

[Greger V. Teigre]

Could you please post to serdev?
AFAIK, any sip or sips uri is valid in record-route, but it is true that 
the examples in 3261 include contain the domain part.
I don't know why record_route_preset does that or whether it is an error.
