Change subject: ns: test if SNS fails when all signalling NSVCs failes
......................................................................
ns: test if SNS fails when all signalling NSVCs failes
As 3GPP TS 48.016 § 7.4b.1.1 specifies this behaviour.
1. do success SNS configuration
2. change sig weight of the seconds inactive bind
3. add second bind to SNS
4. stop reacting to NS_ALIVE on first NSVC (only NSVC with sig weight)
5. expect SNS SIZE
