L3 - Default Steps to reproduce:
1. start tasklist in develop profile
2. login as jonny1
3. create a filter with a criteria "candidate Groups" as key and "accounting" as value
4. save the new filter
3. open filter details for created filter
4. open accordion "Criteria"
5. change criteria key "candidate Groups" to "candidate Group"
6. save the filter
-> The error message "Unable to convert query" will be shown
The problem is that the value is an array, and the criteria "candidateGroup" expects a String. The array should be transformed into a String.
