    Fix error for initializeGnuPG() return value when signing fails.
    
    When the test signing in bridgedb.crypto.initializeGnuPG() fails, the
    return value would be `None`, rather than the gpg interface and the
    signing function, `(gpg, gpgSignMessage)`, or `(None, None)` as it does
    with the other failure modes.  This would cause the EmailServerContext
    to raise a TypeError because `None` is not iterable, and cannot be
    assigned to two variables.
    
    We now return `(None, None)` when the test signing fails.
    
    This is a bugfix on #10385. [0]
