Fixed result of inaccurate assumption

Old fat node code actually created vote object for ineffective vote and updated vote_percent and last_update (but nothing else) for ineffective vote edit. Upsert query to hive_votes changed (and slightly simplified) to reflect that.

As a result of that and previous changes some more tests could be marked as passing.

There is still problem of last_payout being too early by one block and with one edited vote - to be investigated.
