Pootle upgrade

Same problem with Czech language, it is fully translated, but LO pootle
does have many strings that are still in English. No such problem on the
official pootle server. And I checked the .po file in the 2.5.0 tag on
github and it _contains_ the full translation, so no clue why it isn't used.

It's a pity they didn't fix the breadcrumb ordering before releasing 2.5.0,
the project -> language instead of language -> project order is a pain.
