Describe the bug.

We should be able to call load_module without the module_config argument in the case when the config is empty.

This call

builder.load_module("my_compound_op_module", "my_module_namespace", "op_module")

should be equivalent to:

builder.load_module("my_compound_op_module", "my_module_namespace", "op_module", {})
