Describe the bug

Affected versions:
16.0

Additional context
With some debugging I found that in this case the props.value is undefined. By standardFieldProps, value can't be optional and for this reason the schema validation raise the error OwlError: Invalid props for component 'PriceHistoryWidget': 'value' is undefined (should be a value).

Ping for @Yadier-Tecnativa that migrate the old widget into the new OWL system. Any idea?
