* adjust active {item,option} index
We had various ordering issues, and now we properly sort all the notes
which is awesome. However, there is this case where we still use the
`activeOptionIndex` / `activeItemIndex` from _before_ the sort happens.
Now we will ensure that this is properly adjusted when performing the
sort of the items.
In addition, we will also properly adjust these values when
`registering` and `unregistering` items, not only when performing
actions.
