Cannot load CWL definition directly with Python objects using `Factory` class

[fmigneault]

Expected Behavior

from cwltool.factory import Factory
import json 
with open("/tmp/base.json", mode="r", encoding="utf-8") as f:
    cwl = json.load(f)
cwl

Actual Behavior

When the id field is missing and the CWL is provided directly as Python objects, the following error is raised:

KeyError: processobj["id"]

However, the code seems to attempt adding a temporary id (in the form _:<UUID> beforehand) to work around the "missing" document reference when the contents are provided directly. Therefore, the above processobj reference seems invalid.

Workflow Code
