Fetch contact Id Email for workflow tests
Fetch contact Id Email for workflow tests

Why:

One of the workflow tests is failing because the contact `canonical-vid`
that we're using no longer exists.

This PR:

Changes the test to fetch an exisiting contact and use their
`canonical-vid` and `email` in the tests.
