Currently, the standard filter_in methods for date/time/datetime fields would crash for empty strings (AssertionError).
This fix catches empty strings, and treats them as None-equivalent (i.e. NULL).
One could consider to pass an empty string as-is, but this seems invalid as parsers expect either NULL or a valid date/time string for these field types - and even if parsers could handle empty strings for date/time, surely they would return None (what else?), which makes them equivalent to NULL on a round-trip. Hence, returning None for both None and "" seems correct for these particular filter_in methods.
