lok: sc: handling conflicts btw group collapsing and cell editing

Now when a cell is edited, a group including the cell in its range
can't be collapsed.

When whole levels are collapsed all together any group entry including
an edited cell is skipped from collapsing.

Undo/redo of collapsing/expanding has been (temporarily) disabled in
the LOK case, since it could mess things up when a cell is edited and
a group is collapsed because of an undo/redo.
