Person: add an equality check for tags

The equality methods that check for both identity and data fields, 
Person#equals(Object) and PersonCardHandle#equals(Person), checks if all
fields of the Person except tags are identical.

Since these methods check for the equality of both identity and data 
fields, it should test for the equality of all fields including tags.

Let's add an equality check for tags in Person#equals(Object) and 
PersonCardHandle#equals(Person).
