### Describe the bug
Since several weeks (sure enough more than 12) I can't acc…ess my personal contacts anymore. Neither via the WebUI (it just says "no contacts") nor via external Tools (like Outlook Sychronizer - it throws me a 500 error)
In the meanwhile I'v upgraded NC server to 22.2.4 (from .3) hoping that it would solve the problem. And I can't remember clearly if I had updated my contacts version to v4.0.7 or if it happend even with v4.0.6 - could be that this error took place under 4.0.6 as well.
Important notice: I CAN see my contacts if I'd click the contacts icon in menubar in upper right corner.
**To Reproduce**
right now everytime I goto the contacts-app section under my WebGUI I never see any contacts there. But I dunno what I did to make this happen.
