[FIX] web: dateField datepicker don't propagate field options

In a form view (account.invoice), have a date field as:

    <field name="date" options="{\'datepicker\': {\'warn_future\': true}}"/>

Open a record with the field set to a value
Click Edit, click save
Click create

Before this commit, the value of the field of the new record
took the one of the previous record

On account invoices, it resulted on having the popup "The record has been modified etc...."
And it was not possible to create an invoice from another one

this was because we passed the same reference object for the datepicker

After this commit, there is no popup as the field do not take a value from the framework
