[miner] Miner seems to occasionally produce invalid microblocks

[jcnelson]

This came up in #3016. While the node should not crash due to an invalid microblock, the fact that an invalid microblock could be mined is itself concerning. We need to know why this is, so we can stop it from happening.

This is fixed as of 2.05.0.6.0. The bug was that we weren't using enough entropy when generating microblock public keys, leading to duplicate microblock public key hashes.
