Consistency error while adding a new DataFile

[nvn-nil]

Bug report

What is the current behavior?

If the current behavior is a bug, please provide any stack traces the steps reproduce and, if possible, a minimal demo of the problem.

Django model inheriting from AbstractSynchronisedDatastore throws a ConsistencyError while adding a new file (instance creation).

What is the expected behavior?

Adding a new file using the modal doesn't raise exception.

Other information

Explicitly passing the id to Datafile when update_from_store is False In AbstractSynchronisedDatastore seems to solve this for me.

Lines 107 to 112 in 016a28c

	df = Datafile(
	path,
	ignore_stored_metadata=False,
	tags=self.get_tags_from_instance(),
	labels=self.get_labels_from_instance(),
	)

    def to_datafile(self, update_from_store=True, allow_no_location=False):
        ...
        if update_from_store:
            df = Datafile(path)
        else:
            df = Datafile(
                path,
                id=str(self.id), # <-- set the id; idk if this has implications in use cases other than on instance creation
                ignore_stored_metadata=False,
                tags=self.get_tags_from_instance(),
                labels=self.get_labels_from_instance(),
            )

Or maybe add a create_new_instance=False kwarg and create datafile with this.id as the id when called from AbstractSynchronisedDatastore.save method.
