 [21861] sought to improve the template loading behaviour when multiple
 post types are involved, but I don't think it was the right approach.

 1. It creates backward-incompatible behaviour:

 Take a query of `'post_type' => array( 'serie', 'post' )`

 In 3.4, `archive.php` always ended up being loaded, since it was unlikely
 for `archive-Array.php` to exist.

 In 3.5, it unexpectedly loads `archive-serie.php`.

 2. Which template gets loaded depends on the order of the post types, i.e.
 `'post_type' => array( 'serie', 'post' )` is different from `'post_type'
 => array( 'post', 'serie' )`.

 Possible alternatives:

 a) always load `archive.php` if 'post_type' is an array.

 b) choose the template based on `get_queried_object()`.
