The definition of flatten was adjusted in https://github.com/dart-lang/language/pull/2696 such that it better preserves the type information when the type of `e` in `await e` is a type variable. This CL changes the test to expect the behavior of the newly specified flatten. The test has been renamed to 'await_flatten_test.dart'.
