Requesting index.html from root will serve the data browser, not the file itself

Based on https://github.com/solid/userguide/pull/7 I became aware that if you request index.html from the root of a storage, it will return the HTML for the data browser instead of the index.html file itself.

E.g. https://megoth.solid.community/ will give another response than https://megoth.solid.community/index.html. The latter is a handy bug for people who want to edit the index.html file though, so before fixing this bug we need to make sure that users have the ability to edit index.html via the data browser using other means.

With the fix in https://github.com/solid/node-solid-server/pull/1341 we do get this feature though, as users can fetch the contents of index.html through "Your stuff" in the Dashboard. This paves the way for a fix for this bug, which would result in the correct HTML being returned, which is also good for the Source, which will show the correct HTML instead of the default HTML for the data browser.

Überprüfe node-solid-server pull request 1341 und die Behandlung von Anfragen für das Storage-Root und /index.html. Bestätige, dass Benutzer index.html weiterhin über Your stuff im Dashboard abrufen können, und prüfe anschließend, dass die Root-Anfrage und Source das HTML der Datei statt des HTML des Datenbrowsers anzeigen.
