CWL enum requires a name field

[hmenager]

When specifying an enum parameter for a CWL file, the validation of the type will fail, unless you specify an additional 'name' parameter, required in avro but not in cwl.
a workaround is to specify the name field.

This has been fixed in the general case, but not inside a record: #992
