Minor UI improvements.

- close contextual menu after an item is selected
- collapse the search widget after a search request is sent
- show keyboard by default for the editors
- in the search list, if edit or delete is selected in the contextual
  menu, close the search list since its content will get changed.
- enable QueryRefinement in search widget
- do not call super.onNewIntent
- update search.xml to include imeOptions, queryAfterZeroResults, and
  set searchSuggestionThreshold to 1.
