List report on the dashboard with additional GroupBy does not load correctly when "None" is selected in the GroupBy interactive drop-down list.
Steps to Reproduce
Create a List report on Incident table.
Add group by "Active" and additional groupby "Assigned to". Save report.
Add report to dashboard/homepage.
Change group by to "None" in the interactive drop-down list.
Note that the List report is still grouped by Active.
Having no group by default enables the None option to work correctly
