NoDefaultConstructorRef1 was taking a reference of the input, which
meant in the first test it would get a reference to the temporary
created by the 1 literal. A temporary that would be out of scope by
the time we check its value.
Instead add a test with unique_ptr to test we can pass movable
temporaries.
