Server cipher order NPN tests should use SNI

Browse Source 
I noticed the NPN parts of this test were not returning any ECDSA ciphers where I expected them to match the results of the immediately preceding TLS 1.2 test. Found it wasn't using SNI so my test server was using the default domain (snakeoil RSA certificate) instead of the tested domain (dual ECDSA/RSA certificates).
