Fix bots, address duplicate error reporting later.

Fix bots, address duplicate error reporting later.

My CL broke dartk/vm tests because I stopped reporting some errors accidentaly.
I thought I was duplicating all error messages, but turns out that recoverable
errors were only reported in the line fixed here.

This reverts to the old behavior so we can address the reporting issues
separately. Added details to: https://github.com/dart-lang/sdk/issues/30194
