Fix a stupid but pretty bad bug.

When an item did change (its content) but not its identifier and you triggering update(…) then FURRDataSource would not pick this up. This meant a table view would not update the content of its row.

Well… What can I say… now it is fixed.

Technically this change this is a different behaviour. So gave it a new minor version number. (In case you wondered)
