Deirdre Connolly ad3d7fcd49 Split out parsing & validation of test VerificationKey from checking of signature 
Also use fully secure ChaChaRng with a full seed, not just a u64.

Now that we always generate an extra proper VerificationKey for each
Tweak::ChangePubkey case, this /should/ never fail: it also helps split out the
actual verification of the signature from the parsing and validation of the key
itself.

Henry de Valence d8ad15059d Try to prevent ChangePubkey tweaks from becoming a no-op. 
Since we expect the signature to fail if ChangePubkey is applied, we need to
make sure it actually changes the signature test case.
