Incorrect load arguments" in the hook_menu_alter

See: https://www.drupal.org/node/2308913

Accoring to the hook_menu documentation:
"load arguments": An array of arguments to be passed to each of the wildcard object loaders in the path, after the path argument itself.

Now feature_load function receives 3 arguments instead 2: 'feature_name', 'feature_name', TRUE; It does not affect any major functionality or performance, because second argument is always non-empty string and converts to the boolean TRUE, but I think that should be fixed anyway.

Here is the patch.
