This merely refactors a `try`, so it works as expected by the authors.
I'm not sure why the bot didn't trigger this case along with
flutter#188910.

Still work towards:

- dart-lang/sdk#62555.

We are now making the new `analyzer` warning trigger on non-`async`
cases too because that is probably what the code is _meant_ to do.

I don't expect this change to break any tests. If it does, we caught an
untracked error.
