Incomplete test files being found during CI

Description

https://github.com/ampproject/amphtml/pull/35500 renamed the removeAutoplay to removeAutoplay_. In the same commit, there exists https://github.com/samouri/amphtml/blob/363f2bbad12f74d5699451350685e9e6479dfc66/extensions/amp-carousel/0.1/test/test-slidescroll.js, which still references removeAuotplay and tries to stub it. This causes a test failure.

The only thing I can think of is that extensions/amp-carousel/0.1/test/test-slidescroll.js was not found by the test grep, and so it didn’t fail.

Reproduction Steps

1. git checkout 6c7a2f0 (the squash commit)
2. npx amp unit --files ‘extensions/amp-carousel/0.1/test/test-slidescroll.js’

Thanks for poking this thread, @samouri. Not tracking separately, but will send out a PR today to persist the filelist as a CircleCI artifact.

@rsimha: are we tracking https://github.com/ampproject/amphtml/issues/35580#issuecomment-895587167 anywhere? I often need to SSH into a CircleCI node to retrieve the filelist.
