This widget is supposed to be used in list views only (it allows
to re-order the rows by drag-and-dropping them).
Since the new views, the field widgets are shared between all
views, whereas before, each view had its own list of widgets
(and the handle widget was a list view widget).
So if one specifies widget='handle' in a form view, the handle
widget will now be instantiated, whereas before it was ignored.
This rev. fixes two templates making use of the handle widget in
form views.
