Downgrade ns1-go to 2.7.11

Latest changes in 2.7.13 seem to be breaking record creation completely, API returns 500.

Whereas 2.7.12 suffers from a bug that breaks creation with 400 due to
mishandling for tags/blockedTags.

Let's downgrade to 2.7.11 that is working and passing the integration suite, for now.
