fix(state): don't use previous columns ref when getting current cols

[ghiscoding]

• in our current project, if we were to create a Grid View by hidding some columns and then revert to default Grid View and then creating a 2nd Grid View it would reuse the hidden columns from the 1st Grid View even though we wanted to base our 2nd Grid View from the base (which is supposed to have all columns shown)... so basically the issue was that we shouldn't keep/reuse of the columns, we should reevaluate every time
