fixed changes on kleinanzeigen.de:

- Meta did not contain condition and category together anymore, they
removed  the category. Therefore fetching (that is, validation)
failed.
- Now we extract the condition and category directly.
- On top, category now includes the whole category tree.
- unit tests had to be tweaked for this measure.
