This PR fixes #5777

This changes will allow setting an empty value (null, undefined) for fields of type Date/Time through the API.

In the admin panel, it's still not possible to clear the value of Date or Time fields. It is on buffet/core DatePicker component and has related feature request to be able to clear the value of such inputs.

Is there anyone who can confirm this PR?
This is not a big change.
