Old version was not handling being passed instance of a class. Changed to bypass function checking for bilby.hyper.model

• Changes_infer_args_from_function_except_n_args to infer_args_from_function_except_n_args
• Changes infer_parameters_from_function to infer_args_from_function_except_n_args in bilby.hyper.model
