Eliminate redundant double is_function test
When tuple funs were still supported, the idiom for allowing real funs with a certain arity but not tuple funs was: is_function(Fun) andalso is_function(Fun, Arity) The reason that both tests were needed is because: is_function({M,F}) would return 'false' is_function({M,F}, Arity) would return 'true' In 53ec991d19, is_function/2 was updated to only return 'false' for tuples, so the call to is_function/1 can be removed.
