res_pjsip_nat: Don't assume a Contact header will always contain a URI.

Browse Source 
If the 'rewrite_contact' option was enabled and a Contact header was received
which contained a '*' a crash would occur.

This change makes the res_pjsip_nat module ignore the Contact header if it
contains only a '*'.
