nodequeue_view_nodes is throwing notices

Found a pretty basic bug with nodequeue that is causing a lot of errors on our site.

To replicate:

- Use a fresh Drupal 7 install.
- Install nodequeue
- Create a nodequeue, and assign 3 basic pages to the nodequeue
- Edit themes/bartik/template.php, and add the following code into bartik_preprocess_html

$nodes = nodequeue_view_nodes(1, FALSE);

You can place this code anywhere else, a module or whatever, the outcome is the same. I get errors:

Notice: Undefined offset: 3 in _field_invoke_multiple() (line 328 of /Users/thomaswilhelm/Sites/drupal-7.38/modules/field/field.attach.inc).

This is caused by the nodequeue_load_nodes() function, this returns nodes indexed 0,1,2,3 etc. due to the following lines:

// Return numerically indexed array for backward compatibility.
// @todo reevaluate this.
return array_values(node_load_multiple($result));

changing this to:

return node_load_multiple($result);

Fixes the error for me.

This I believe is because node_view_multiple() which is called in nodequeue_view_nodes() expects the $nodes array it receives to haves keys which match the node ID's of each element.
