Process scrubbed response so created fixtures pass

Because `create-fixture.ts` and `fixturedActions.test.ts` process
different responses (unscrubbed and scrubbed) they can have different
outputs, e.g., different mutations. The differences cause freshly
created fixtures to fail, requiring a subsequent `--updateSnapshot`.

This change makes `create-fixture.ts` process the same (scrubbed)
response as `fixturedActions.test.ts`, resulting in the same outputs and
the fixture passing.
