sccp: set titan.SCCP commit: use fix for localRef == 0

Use this fix in our tests:
https://github.com/osmocom/titan.ProtocolEmulations.SCCP/commit/17a894fc6620a0df11d0d98c897fb66168276b16

This allows osmo-hnbgw to start out with SCCP local reference == 0
without that causing test failure.

'Related' patch below happens to have that effect, and it was *really*
hard to find out why th the tests failed. It seemed like I had messed up
osmo-hnbgw, but then I found out it wasn't my fault at all.
