Fix 2 small issues in sporks module (#2133)

Browse Source 
* Fix a crash when someone tries to update sporks without specifying `sporkkey`

Before:
Crashes with `Assertion failed: (fValid), function GetPubKey, file key.cpp, line 156.`

After:
Fails and prints rpc help for `spork`

* Silence logging in CSporkMessage::CheckSignature() a bit

CMessageSigner::VerifyMessage() failure is not really an error
if CHashSigner::VerifyHash() below passes with no issues.
No need to log this.
