Issue #47 - test database_api get_payout_stats fail

0.23 version had hive_posts.curator_payout_value containing VESTS, new one is raw number leading to

/hive/utils/normalize.py", line 79, in parse_amount
  raw_amount, unit = value.split(' ')
ValueError: not enough values to unpack (expected 2, got 1)

There would still be error if it was VESTS, because it is called from sbd_amount which expects HBD. Also it makes no sense that just that one column is a string (but that is unrelated to the changes).

Example of test failing due to that problem: condenser_api.get_blog

That problem most likely needs to be corrected prior to merge.

There is an improvement with regard to votes with rshares=0 - they started to actually show up in results - however their time and percent are frequently wrong.

Example of test failing due to that problem: condenser_api.get_discussions_by_promoted

That problem needs to be investigated but should not stop the merge.

condenser_api.get_trending_tags is better (same set of tags as in pattern) but everything else, incliding number of posts and comments (obviously payouts as well) is different. To be investigated.
