Test could run with every provider

Faker has (many) providers which email is returning invalid emails.
But, as Faker does not have tests for every provider this is not noticed.
Well done or not, I've created a test that will run every existent provider. Off course this test will fail right at the beginning.
This could also be useful to test a unique "toAsscii" method that would be used in every provider.
Anyway, this is just me playing around (I enjoy it anyway) and maybe you have a better idea or already have though of this.
Feel free to close this if useless and sorry for wasting you time.
