Click on a non existing contact results in a endless spinner

[realthargor]

Steps to reproduce

1. Open two browser instances and navigate to contacts
2. Remove contact X in browser A
3. Click on contact X in browser B

Expected behaviour

Removed and clicked-on contact disappears.

Actual behaviour

Angular-app shows a spinner and does not return.

Probably because the REPORT-Request is answered with a 200 and an empty result, which is unexpected.
