Fix syntax problem in smoke test config

[delucchi-cmu]

Change Description

Smoke tests currently failing, as the workflow tries to send an email that doesn't need to get sent. If the email really DID need to get sent, this would fail, too, but this should at least show green on upcoming changes to the LSDB Workflow dashboard.

See lincc-frameworks/lf-workflow-dash#93
