bug#22359: 24.5; EasyPG selects wrong key when revoked key is present

The package EasyPG does not filter revoked keys.

I have two keys in my keyring with the same email address. One is
revoked and one is not. I expect EasyPG not to even consider the revoked
one. Instead, it tries to use it and errors with:

Opening output file: Encrypt failed, Unusable public key: REVOKED-KEY-ID; Exit
