  Warning produced when adding/ editing an image gallery block

Bug description:
  A warning message is being produced when adding or editing an image
  gallery block (see attached screenshot)

  To reproduce:
  1) Log in as any user and create a page
  2) Edit the page and select image gallery block, select some images, press save
  expected results:
  The page displays with an image gallery and no warnings
  actual results:
  The page displays with an image gallery and warnings:
  "[WAR] 98 (blocktype/lib.php:2104) stripos() expects parameter 1 to be string, array given"

  This issue is occurring because the javascript function
  get_get_javascript_javascript($jsfiles) in blocktype/lib.php has been
  set up to expect a non-empty file entry in its logic in its foreach
  loop. This is an issue in artefact/file/blocktype/gallery/lib.php in
  get_instance_javascript() which passes down an array with an empty
  file entry:

              array(
                  'file' => '',
                  'initjs' => "$('#slideshow{$blockid}').on('slid.bs.carousel', function () {
                      $(window).trigger('colresize');
                  });"
              )
  The get_get_javascript_javascript($jsfiles) should be amended to handle the above input.

  Version: 20.04dev
