Symfony file structure changed in Symfony3

[einorler]

In Import service importComponentTranslationFiles() method, we are importing some symfony components translation files:

TranslationsBundle/Service/Import.php

Line 172 in 5190dc9

public function importComponentTranslationFiles()

Problem is that in Symfony3 the structure of some of these files is changed and the tests are throwing errors when trying to import them.
