fix(spike): remove broken TestDoCreate_HappyPath

The handler package has no TestMain to initialize DB/fixtures, so the
test panics on nil pointer deref when run via mage test:feature (which
walks every package) even though it was hidden when running only
mage test:web. DoCreate is already covered end-to-end by
TestHumaLabel_Create_ReadOne_via_OAS31Route in pkg/webtests.
