[Bug] Count (Not) Empty not returning expected value for checklists

[eric-hansen]

Bug Description

Count (Not) Empty aggregates for checklists does not make clear sense what it is trying to count.

How to Reproduce

Add a checklist column to a kanban board, and then for sums/aggregates choose count (not) empty.

Expected Behavior

I would expect "Empty" for the first column to be 5 (the # of items in the checklist), while "Filled" for the second column to be 0 since nothing is checked, or completed for that matter.

Operating System

Linux, Windows

AppFlowy Version(s)

0.8.x client, self-hosted cloud instance

Screenshots

Additional Context

I don't know where to find the version of the desktop client, but I started using AppFlowy at version 0.8.0, so it's pretty recent/new.
