Update German test_search_and_parse to accept January for parsing of

'Die'

It is searching a German string for dates and asserting that when it finds the word "Die" in the string, it should be parsed as `datetime.datetime(1999, 12, 28, 0, 0)`
Similarly, my change makes this `datetime.datetime(1999, 1, 28, 0, 0)` instead. I don't speak German, but as far as I can tell "Die" just means "The" so I have no idea why it is even matching it. In my opinion, this could be a bug with the search identifying a non-date word, and so I can't really guess as to what a sensible result would be. For the sake of simplicity, I also just updated this test to accept January,
