'auto' and 'display-auto-control' attributes missed when search is modified

Steps to reproduce:

• Create a page provider
• Configure the form and result form at View Designer
• Modify your bundle file adding auto and display-auto-control in your nuxeo-search-form tab

  <!-- Contribution of element 'nuxeo-search-form' for slot 'DRAWER_PAGES' -->
  <nuxeo-slot-content name="commercialResearchSearch" slot="DRAWER_PAGES" >
    <template>
      <nuxeo-search-form provider="commercialResearchSearch" schemas="dublincore,CommercialResearchSchema,file" search-name="commercialresearchsearch" name="commercialresearchsearch" page-size="40" selected-search-idx="0" auto display-auto-control></nuxeo-search-form>
    </template>
  </nuxeo-slot-content>
  

• Deploy your changes in your environment. The changes are deployed ok.

• Back to view designer
• Access to your search form.
• Apply some change to your search, e.g. Change the icon or the order.
• Save your changes

The bundle file is overwritten and the attribute 'auto' and 'display-auto-control' are removed.

NOTE: My suggestion: Add two checkboses in the search configuration page to set the auto search and display auto control features
