We took the decision to decouple the selection state from the data. This
means that the selection state does not always stay in sync with the
data, but the resulting output should be correct.

In this case `allSeletedRows` and `someSelectedRows` were calculated
based on the size of the selected rows which was wrong, because there
can be outdated values in there. Updates the `useTableSelection` hook
to make sure that those states reflect the what is in the data. This
will cause extra computation (which is memoized) but there is no other
way to maintain consistency.

It might be possible to update `useSelection` accept the set of
selectable items, but the extra computation will still need to be there.
