[ ] @igorbajena Fix the bug that "add existing WissKi" function do not work correctly
Feedback from Tassilo Striedl (LMU):
"The "add existing wisski entry" function did not work correctly for him. Two wisski entries he created were not available for selection when he wanted to use them in a later section, even after I had completed the upload and wanted to add this information via an edit afterwards, so the original wisski entries had already been uploaded."
