Error when fetching historical data from Snowflake with null array type fields #3963

Expected Behavior

When fetching data for an entity that has no record for a feature view with an array type column it should return None and not throw an exception.

Current Behavior

When fetching historical data from a Snowflake offline store it'll throw an exception when an entity has no record in a FeatureView with an array-type field.
