[IMP] web: add onWillStart in calendar's model

This commit allows to define a `onWillStartModel` method in the calendar controller that will be used as `onWillStart` option of the calendar model.

Purpose
--------

The related enterprise PR introduces a new "item calendar" feature in Knowledge that allows to embed calendar views using article properties to display these articles in the calendar.

To do so, one needs to modify the fields mapping before the model is loaded for the first time, so that the records are fetched using the properties in the search domain.
The `onWillStart` option of the `useModel` function is perfectly suited for this.
