ava/no-ignored-test-files - "AVA ignores this file." false positive when using ava in a monorepo structure.

[Mathrio]

I'm trying to use AVA in a monorepo but i'm not able to get this eslint plugin working.

I'm able to execute my tests but the plugin thinks AVA is ignoring the test files.

Here is a small repo(https://github.com/Mathrio/ts-monorepo-starter) to reproduce.

Just build it and then do npm test to see that the test passes. If you look into packages/package-a/test/sample.test.ts you will see the error.
