fix: dont defer return of non-async val in async fn

Doesn't appear to be necessary as the fn doesn't take a callback and the
result can only be accessed via `then()` method or `await` (the fn has
to be awaited either way in order to access the return value, regardless
of whether the function finishes immediately or not).
