Should allow use of ES6 getters and setters.

[scottwrobinson]

When using get and set methods in a Document, the Proxy correctly intercepts the call, but then any gets/sets done within the intercepted get/set is not intercepted by the Proxy.

Example:

class User extends Document {
    constructor() {
        super('user');
        this.firstName = String;
        this.lastName = String;
    }

    get fullName() {
        return this.firstName + ' ' + this.lastName;
    }
}

Calling user.fullName returns the string representation of the String object, which is the schema definition, and not the actual values of firstName and lastName.
