Problem

I have strange error on new Date with potential undefined property

The user.createdAt is defined in an interface with :

createdAt?: Date

Reproducible Case

1. Create an property with potential property undefined like :

   test: { testVal?: Date } = {
     testVal: new Date()
   }

2. Try display that property with {{ new Date(test.testVal || 0) }}

This is because NewExpression is currently not handled by template interpolation service. I'll add support for it.
