3.48.1

Fixed

• Changed the way the search action generates links to the results. It used to
  consider every item editable, but would throw an error if it wasn't the case.
  It now uses the getSearchResultLink that choses the best way to link to a
  search result; eg. edit if available, or show.
• crash when submitting a form with only spaces in a required field
• redirecting to a blank tab after saving an object
• modifying form values changing tabs
