Deleting a file while the ember server is running throws a build error.

So far I've noticed this for files in app/helpers/** and app/templates/components/** but not app/components/** files.

Hey @colenso 👋 I just tried to recreate this issue in our test suite and I couldn't get it to fail 🤔 are you able to put together a reproduction for us?

We've encountered the same issue. We deleted a template/*.hbs file and the build server threw an error. Here's the relevant stack trace

Module build failed (from ../../thread-loader/dist/cjs.js):

This is the interesting line

ENOENT: no such file or directory, open '/redacted/node_modules/.embroider/rewritten-app/templates/settings/password-reset.hbs/password-reset.hbs'

It looks like the filename has been appended twice at the end of the path.

We're using

    "@ember/test-helpers": "^2.9.4",
    "@embroider/compat": "^3.4.0",
    "@embroider/core": "^3.4.2",
    "@embroider/webpack": "^3.2.1",

I've been running into this recently a fair bit — pretty much every time I switch a branch or rebase (usually because there's almost always something deleted / moved).

From my limited testing, it seemed like it only failed if the file that is deleted was imported somewhere. Template files being deleted didn't seem to break anything (which is a bit different from the original issue!)
