improve digest module (killed isnonce method)

Prior to this change the digest module would check whether a nonce
looks like a nonce, verify the response and then verify the nonce.
This left a bit more room for brute forcing passwords, as the same
nonce could be used in arbitrary many tries and a stale response
would indicate an authentication success. Now authentication is only
tried for valid nonces. This also makes the NonceStoreBase.isnonce
method superfluous.
