beam_load: Fix faulty assertion in module_info(native_addresses)
Commit 64ccd8c9b7a782ca777ca4649dbb1f4a1ef00bce introduced BIF stubs. The stub functions were not actually remove the loaded code, but the name of the function in the func_info instruction was changed to [] to mark it as invalid. The actual code for module_info(native_addresses) did not need to be updated (a BIF stub can never have a native address and a function without a native address will never be included in the list), but the assertion that the name is an atom is no no longer correct.
