Set number presentation to restricted if CEP participant has invalid Uri.

Per RFC5767, a SIP uri can contain the hostname "anonymous.invalid" if
the identity of the caller is unknown (e.g. blocked caller ID).  Added
code to pick up on this and set the number presentation for CEP
participants matching this pattern.  This prevents the
anonymousA@anonymous.invalid participant names associated with caller ID
blocked numbers from showing up.
