CAM: Fix creating Helix on Prototype

For the "Op Defaults" from the setup sheet the operations get created
with a `OpPrototype` instead of a real document object. This prototype
provides only a small subset of FreeCAD's document object API. When a
new Job is created via the GUI, each registered operation is created
with such a dummy to populate the setup sheet panel. And if such an
operation uses document APIs not provided by the prototype, the enire
job creation fails, see #17871.
Unfortunately we don't have tests for the GUI part, where all the
operations are regsitered and thus the integration with all of them
could be verified, this I just created a local test for the helix, where
the actual issue was reported -- this can be verified with headlessly.
