Default value not set on date when null is passed in.

[avishaan]

When I set the value of a date property whose default is set to Date.now to null, the date is not populated and instead populates as 'null'. I created a quick repo you can run to check this out. There is a lot of overhead because I tried to cut it from my existing code and was in a hurry.

This is the result, I expected the default date where it says null.

Here is the store in the database. I expect null to equal the default date.

null is a valid value for a Date property, unless you specify required. Defaults only get set if the value is undefined, not if its falsy.
