deleting a vertex does not set feature.modified, this is a regression since in OL 2.10 a WFS transaction would include all fields, but 2.11 is smarter in the sense that it filters out fields that have not changed in the Transaction XML, which in this case, i.e. deleting a vertex, results in no geometry in the WFS transaction, r=tschaub (pullup #3463)
