Definition of removal is providing a `credentials` list on launch
that lacks a type of credential that the job template has.
This assures that every category of credential the job template
has will also exist on jobs ran from that job template.
This restriction already existed, but this makes the endpoint
fail instead of re-adding the credentials.
This change makes manual launch congruent with saved launch
configurations.
