refactor(uploader): Do not use arguments in constructor

[tvdeyen]

What is this pull request for?

Using custom elements like this is no compliant to the spec. You must not have arguments passed to the constructor as the browser won't be able to do that.

This prepares these file to be tested with Vitest instead of Jest.
