Rename a file only changing the case causes the test to be listed twice.

[grantmcdade]

Describe the bug Renaming app.test.ts to App.test.ts causes both to be listed in the explorer. They both have the same tests but all of the tests in app.test.ts fail with the text 'Are there tests with the same name?' among other things.

To Reproduce Steps to reproduce the behavior on the example project:

1. Run the tests
2. Rename App.test.ts to app.test.ts
3. Run the tests

Expected behavior App.test.ts is no longer on the list.
