Clicking on a bar/wedge doesn't filter the new index page

[rouilj]

When clicking on the bar or wedge for a single group chart (it works for stacked and multibar charts), the URL is incorrectly formed.

I see:

http://localhost:8080/demo/issue?@template=index&@columns=id,activity,title,creator,assignedto,status&@sort=-activity&@group=priority&@pagesize=50&@startwith=0&status=-1,1,2,3,4,5,6,7&@filter=status,priority,priority&[%27priority%27]=urgent

Note the [%27priority%27]=urgent (%27 => ') It looks like the list of groups is being assigned and not the group member. Replacing ['priority'=urgent with priority=urgent in the URL properly filters the drilldown.

The commit to fix this should also modify the test code created by @varshi-123 to detect the incorrect URL.

I think my recent changes which I made to solve issue #62 created this bug and I have made some changes into file and have push those into main. This solves the problem so kindly review it. commit - 7de7fd9
