Re-exported templates from template-only components in in-repo addons are incorrectly removed

[robinborst95]

Within our in-repo addons, we have a structure as follows:

app
  templates
    components
      nested
        foo.hbs
      nested-2
        bar.js

with bar.js a file with a re-export like:

export { default } from '../nested/foo';

When running this codemod, such re-exported templates are removed, which leads to missing component errors. Since we have a lot of components, this resulted in having to check all removed templates to see if they were removed correctly or not 😕

Within the app directory this seemed not to have been an issue though.
