The pre-1970 information for Europe/Amsterdam was removed from the main distribution. This time zone is tested against in https://github.com/chronotope/chrono-tz/blob/444eb4dcb15a2c8837163e224785902d989f4d3c/src/lib.rs#L339-L340

I guess the test should be removed rather than explicitly ensuring that the wrong information is returned?
