We have a problem with KisDoc2::undoIndexChanged. The problem is it
notifies listeners wrongly! Its 'idx' parameter refers to "the command
that will be executed on the next redo()", but *not* a command that
was undone/redone right now! It means that our mechanism of notifying
listeners is broken. The bug has been reported by Marc, as it affects
transform tool.

I don't know how to fix it as it seems to depend on Qt's QUndoStack
much. So i just wrote the test for the problem. What do you think
about it?
