Fix flakey hbase unit tests

[BenFradet]

fixes #294

[BenFradet]

I'll rebase once #299 is merged

[BenFradet]

I think I'll just remove the multiput property since multiput is not implemented in the hbase store.

[BenFradet]

I'll run the tests 10 times to see if the hbase tests are fixed

[BenFradet]

@johnynek ran the suites 10 times and no hbase tests failed, tell me when you want me to rebase.

[johnynek]

This looks great, thanks so much. If you rebase, I'll keep running the tests until elastic search passes. :(

[BenFradet]

Could you merge #299 first since I checked out from this branch to avoid having to go through the humongous quantity of logs? In the meantime I'll remove the unnecessary commits.

[BenFradet]

@johnynek done 👍

Thanks!
