Some of these tests had failed because when you don't supply a ref_date it will calculate the age today (using Sys.Date()), this meant that the 'people' are now older than when we first wrote the tests, so age_from_chi no longer returned the expected age.
I wrote a small helper function to work out what the 'expected age' should be now, given the date we first set the tests.
