ns: add TC_sns_bss_remove_bind_fail_sns to check SNS fails correct when removing a bind 

This TC produces an abort of the ns2 dummy by the memory sanitizer.
Test if SNS fails when removing a bind which has the last valid connection.
The ns2 has 2 binds, ttcn3 1 bind. There are 2 NSVCs.

Bind -- NSVCs -- Bind.

(ns2)      (ttcn3)
1*-----------*1
            /
2*-broken--/

Remove the 1st ns2 bind after the other NSVC has failed.
