Get the test to pass when pair's default constructor creates two instances of

the member classes.

With some standard libraries I was getting two copies of the object after
creating a default pair, probably because it was creating an instance for its
default parameter. So only test after creating the pair object - since it isn't
our concern how many instances that creates.
