Charter occurs multiple times in fond overview

Created by: StephanMa

As mentioned in the email communication, the charter A_III_3 (http://monasterium.net/mom/DE-FWUBHGW/LSU/A_III_3/charter) occurs multiple times when browsing through the fond (http://monasterium.net/mom/DE-FWUBHGW/LSU/fond).

While entering the preview of the charter and navigating in the preview, the charters just appear once.

I tested several states of the charter-preview.widget.xml and it seems that the error was introduced during the additions of IllUrk. I resetted the state of the widget to https://github.com/icaruseu/mom-ca/commit/395a111d753c6d1584ac80b551872a5e3cc28718#diff-6eee8c5774b738e094c2c249fe1ed314 and it works.
