Describe the bug.

PR #451 appears to have broken BuilderProxy::load_module_from_registry when an unserializable object is passed in with the config.

I haven't reproduced this in MRC yet, but in Morpheus the dfp_integrated_training_batch_pipeline.py will pass in a datetime object in the config. In recent versions of MRC this now throws, not sure how it was handled prior to this.

The issue is that prior to PR #451 cast_from_pyobject would return a json null value for unserializable values, now it throws.

Closing this in favor of fixing on the Morpheus side.
