Before this rev., there was a race condition when the user did
some changes on a form view (triggering an onchange), saved and
clicked on the breadcrumbs to leave the form view (before the
onchange returned). As a consequence, the dialog telling the user
that there are pending changes was displayed. This mostly occured
on the main_flow_tour since the removal of an unnecessary check,
and could be reproduced manually on a slow network.
Basically, the check if there were pending changes was done too
early (before the view was actually saved).
