Cannot exclude stories.ts file from auto import

[drik98]

Describe the bug

This describes the same problems as in #407

Excluding files with a regex does not work. In my case I also want to exclude all stories files because they are only used for storybook and often times story names overlap.

I added a failing test case to highlight the problem in my fork.
