The fuzzer test for NodeRegistrationOptions is defaulting the CRISocket member.
This is a left over from the times this member was statically defaulted in the
config. Now that the member is dynamically defaulted, setting CRISocket to foo
can cause issues to get undetected by the fuzzer test with this member.
The resolution is to stop setting CRISocket in the fuzzer test.
