annotate --delete doesn't respect ignore_unknown_models

[alexeyr-ci1]

I have a project where many files in app/models are not actually models. With 'ignore_unknown_models' => 'true' they are skipped by bin/annotate as expected, but

alexey@DESKTOP-41AVESA:~/shaka/blade$ bin/annotate -d
Traceback (most recent call last):
