The on_attach_callback methods on the widgets (comming from a tag
'widget') of a form renderer were not called at an appropriate time.
They were not called at all or called before the widgets were actually
in the dom. This was made manifest in the dashboards that generally use
pie charts widgets. Each time a pie chart widget is renderered,
a new canvas with a unique id is created. The above mentioned problem
explains why Chart.js was not able to acquire the canvas contexts: they
are obtained by looking for a specific id in the dom.
The present commit fixes that problem by doing in the class FormRenderer
what was already done correctly in the child class DashboardRenderer and
remove the unapropriate calls to on_attach_callback in _renderWidget.
