Fix failing SchemaReferenceResolverHelper unit test

[JFisk42]

Problem Statement

There is a test which normally fails the first time it is run in CI. This isn't a blocker as our unit tests are set to run a second time to allow for some flaky tests. This tests fails the majority of the time so an average savings of 2-5 minutes can be gained per prime router build.
