[reSIProcate] Route Set problem with Update in resip 1.1 RC1

This is interesting. I do not think it would be correct to change
the Record-Route stack to reflect the Route set in the dialog.
Obviously something in the middle is confused if this happens, and
changing the Record-Route stack in the response is liable to confuse
it even further. Both endpoints should just ignore the Record-Route
header-field-values entirely, I think.
Any other opinions?
Best regards,
Byron Campen
