Avoid passing a nullable value to Future<nn-type>.value or Completer<…

…nn-type>.completer.

This is cleanup work required to start enforcing this with static analysis, as per dart-lang/sdk#53253.

Real quick this issue is that this code is unsafe:

```dart
void f(Completer<int> c, int? i) {
  Future<int>.value(i); // Ouch!
  c.complete(i);        // Ouch!
}
```

This change should be a no-op. Adding this explicit null-assert ensures that any exception is thrown right at the null-assert.
