Open favorite folder from sidebar shows root folder content

[MorrisJobke]

• have folder abc
• mark it as favorite abc
• click on the item abc in the left sidebar under favorites
• expected: see content of abc in the file list
• actual: see the content of the home folder in the file list

It is also noticed that there are two webdav requests: first one for the folder abc and then one for the home of the user.

Happens on 14.0.4 RC 1, 15.0.0 beta 2 and master
