Broken typescript config when using extends.

Summary
Broken tsconfig when using extends. Tests are running perfectly when pointing to config without relative extends.

Hi @george-kats-e thanks for opening this issue and sharing your configs. Should be a relatively easy fix.

@danny12321 if you feel up to it you might want to pick this up?

EDIT: @george-kats-e workaround for now is to remove the "tsBuildInfoFile": "./buildcache/tsconfig.tsbuildinfo" fro your config.

Or you could try changing your tsconfig.stryker.json:

{
  "extends": "./tsconfig.json",
  "compilerOptions": {
    "skipLibCheck": true,
+   "tsBuildInfoFile": null
  },
}
