LPS-41820 Fix broken tests

Hey Eudaldo,

There were some broken tests on trunk which were LAR related as well, Brian asked me to investigate.

I've figured that changes in the JournalTestUtil caused the problem, and I've created a fix for it. The only difference in my commit is that I've called the createLocalizedContent method on the content parameter which will eventually produce an XML.

I wanted you to check this out if you see any problems with it, since you created the original change, if you think it's fine, please push this to @juliocamarero.

Thanks,

Máté
