commands: Fix flaw in the livereload logic

I guess most commonly an issue with TailwindCSS editing in templates:

* Build changes both CSS and index.html => reload OK.
* Build changes both CSS and index.html and some other files => only CSS reloaded.

The above would fix itself with one more edit, but that's annoying.
