Show image-upload errors on /admin/advanced/tools (#16448)
* Show image-upload errors on /admin/advanced/tools

* Simplify error handling

This also makes the error message consistent with the rest of the admin
validation errors, so it's probably better even if it doesn't look as
flashy.

* Remove obsolete clearTimeout call

We aren't setting this timer anymore
