getKeyForAddress Test

Currently the tests for getPublicKeyForAddress() and getPrivateKeyForAddress() receive and accept an empty array. It looks to me like the test keys were generated with 'whiteout.test@t-online.de' as the email as opposed to 'test@t-online.de'. Changing the address fixes the result when searching for public keys, but searching for private keys seems to remain broken.

Apologies if I'm missing something basic, it's 5am local time ><
