Resolve #3366032 "Problem with filter"
This ticket provides a new way of managing the groups of filters at the class src/Plugin/views/query/ViewsJsonQuery.php
At development we tested:
- View with no filter at all
- View with two filters with AND condition(and no group condition). This is a 1 group filter case.
- View with the previous filters and another group with two filters using OR condition. This is a 2 group filter case.
It provides a solution for issue reported here: Problem with filter not working
