CI fixes

Attempt at fixing tests in the restructure branch

The datewidget has a dict of options and dumps it in javascript.
Problem: the order of options is unpredictable because it doesn't use an
OrderedDict.

Note: it **must** be kept loosely coupled with other modules in this
repository. It was merged here just to remove the burden of having
several repositories to manage: volunteer time is precious.
