Title: Fixed for allowing empty translation.

PoFileLoader should accept empty translations.

PoFileLoader calls array_filter just before returning the $messages thus filtering empty translations.

For Drupal we need to be able to load and then translate incomplete PO and POT files.

(this is part of [[WIP]: Allow Drupal to use Translate component](https://github.com/symfony/symfony/pull/4249))
