Fix protocol version check in staticSynchronizerParameters

The 37 was buggy, we accidentally changed that as part of a replacement from 36 to 37. The more important part is that the protocol version is taken from the successor synchronizer id which is the part that has blown up on 36.

I can't write a test for this as we don't support PV 35 anymore so I can't make the if condition fail.

I also want to fully remove the local protocol version config but I'll do that in a follow up. And as part of that probably also just remove the protocolVersion >= v36 condition as it's redundant on main.
