Very niche usecase, but still:
\- Create a planning shift, set a recurrence for ever.
\- Go few occurences later (form via kanban) and set...
...recurrence type to "Number of Occurences",
...recurrence nmber to 1.
\- Save.
The write method will update the recurrence
so that it only contains only one occurrence.
Consequently, the record you just updated is deleted.
Then we try to fetch the record to display its form again.
Because de read returns [], _fetchRecord rejects the promise,
and we're stuck.
So, in this commit, we make `FormController.saveButtonClicked` call
`Record.save` with its params, so itself can be called with throwOnError,
and the potential error catched.
We all so cover the case where `BasicModel._fetchRecord`
returns `Promise.reject()`, in `BasicModel.save`.
Also, `Record.save` has an object as a default value for params.
When we call it from `FormController.saveButtonClicked` with params,
say params is an empty dict, the default value will be lost.
Istead of overriding this object, this commit only overrides/adds
the key of the object we give `Record.save` if any.
Also, when investigating on that, we jsut noticed that,
when you click save on a form dialog,
it reloads the record before closing it, which is useless.
