Fix clear button does not clear all criteria, depending on element

Create a custom search page provider, layout, button and deploy using the following criteria:

• a data of type text, such as dc:title
• a data of type multivalued directory (to be mapped in Designer code view as nuxeo-directory-suggestion, see NXS-4553)
• a data of type date (such as dc:modified)

Invoke the search button, and show it fully functional using the text, date and directories values.

Clear the data: the text fields are wiped out, but neither the directory values nor the dates are, but the data does not remain as filter => this is a custom search form UI issue.

Regarding the directory values, you can clear them with hand as a workaround, but you can not the date field for which no workaround exists except canceling the search and launching a new search for the display to be re-rendered
