Title: Remove from start/end dates if tz is not None (#7901, #7835)

Below fixes date_range when input dates are localized. In that case inferred_freq is not None and so the dates do not have their tzinfo removed. This causes a fixed offset to be applied when the range is created. If tzinfo is removed, they will be correctly localized.
