These date parameters cause problems. Cypher doesn't have a date type, and the Neo Go driver gets confused when trying to load a string value into a date field.

The SQL driver had a similar problem with NULL dates. We can probably write a patch for the Neo driver along similar lines: https://github.com/go-sql-driver/mysql/commit/73f5a73c6460b2d65683da74ab6f2f8d8aae9989
