Subject: js: Fix display when there are 0 search results

* js/controller/packages.js (guix.packages.packages): Default to empty
  array.
* js/model/packages.js (guix.packages.Pager.currentPage): Always return
  an array
* js/view/packages.js (guix.packages.view): Show spinner when there are
  0 packages loaded from the server, not when there are 0 pages of
  results.
