registry-user.controller.getUser does not properly check user is of the same org

[emathew5]

When registry-user.controller.getUser is called by the registryUser endpoint

router.get('/registryUser/:identifier',

it does not grab that identifier(a user UUID)'s org
instead it calls

const org = identifier
      ? await repo.getOrg(identifier, true)

which attempts to grab the org using the user UUID which will never be correct.

To-do: Add integration test to check for this edge case
