Validate tlog entry when verifying signature via public key.
Previously, when signatures were validated via public key, we only checked for the existence of the tlog, but didn't actually validate the entry. This refactors the code to ensure both cert + public paths go through the same tlog entry validation. Signed-off-by: Billy Lynch <[email protected]>

It looks like trillian makes some fake inclusion proofs https://github.com/google/trillian/blob/3d7922afdce9fd0144e16aae08bea061c0ad1aee/merkle/logverifier/log_verifier_test.go#L45 for testing -- maybe we can do that?
