Unknown formatter secondaryAddress does not exist

[pedzed]

Summary

I expected $faker->secondaryAddress to work, but it doesn't, whilst it is documented in the README. A possible reason is that I'm not using en_US as locale, but rather nl_NL. But I wouldn't expect an error, even though I am not using the default en_US locale.
