Add search of mail templates in symfony-bundles (#66)

If you used Symfony bundles to add multiple themes, they weren't found when the template finder searched for the matching theme of the salesChannel resulting in it taking the first theme in alphabetical order.

When no Shopware app or plugin was found, it now searches for matching bundles.
