This test now fails in my environment, I'm getting other dates returned from the date function than when I wrote these tests. 
I believe it's because the date generator in [/src/Faker/Provider/sv_SE/Person.php#L140] (https://github.com/ulrikjohansson/Faker/blob/d301e2ba8e6ef585ae03cf5202d109ae773ef52c/src/Faker/Provider/sv_SE/Person.php#L140) is getting a different max range. I could just not use fixed values to test for, but then I'd have to use a copy of the actual Luhn function in Person.php to check with.

What is the best way to test this?
