fix(resource loading): don't load root resources twice if homeFolder is set

[fschade]

Description

in some cases it could happen that resources get loaded twice.
This happens in the Personal view (all files) if a homeFolder is configured.

This pr takes care of it by returning early before any root resources gets loaded.
This is not a final solution and should be considered when working on the architecture in general.

found a bug: when you're in the root folder of All files you don't get redirected to the homeFolder anymore when clicking on the All files menu item.
