Workflow validation doesn't catch syntax error in 'Name' field in SubWorkflow

[helen-fornazier]

If a workflow has an invalid name, e.g. img-test_independent, executing this workflow fails as expected:

[Daisy] Running workflow "img-test_independent" (id=zy2s1)

[Daisy] Errors in one or more workflows:
  img-test_independent: error validating workflow: workflow field 'Name' must start with a letter and only contain letters, numbers, and hyphens

But if we use this bad Workflow in a IncludeWorflow or SubWorkflow, validation doesn't fail.

For IncludeWorkflow and SubWorkflow the name is overwritten with the step name, so the invalid name is never used.

I'm going to close this as the name fields are ignored (along with most top level fields) for subworkflow and include workflows.
