Title: Fix: option 'defaultValue' for 'date' property should set 'DEFAULT = now() 

consider a model
```js
Project.hasMany('members',
User,
{ since: { type: 'date',
time: true,
defaultValue: Date.now
}},
{ reverse: 'projects'} );

```

I gets an error 'column "since" is of type timestamp without time zone but default expression is of type bigint' while syncing the databse with my postgresSql db
setting
```js
defaultValue = function(){ return new Date(); }
```
didn't solved the problem. So I fixed it.
I am not sure whether it is the right method
