This PR simplifies the tests for the calendar attribute on the dt accessor when using a datetime64[ns]-dtype DataArray. Instead of creating random-valued datetime arrays, we can use arrays of zeros (i.e. 1970-01-01), since the values of the datetimes should not be relevant to these tests (only their type matters).

I suspect this should address #6906, because it eliminates the need to convert to datetime64[ns], though I still feel as though there is a more fundamental pandas issue lurking there.
