HVULoss and LoadHVULabel should be unittested.

See https://codecov.io/gh/open-mmlab/mmaction2/pull/235/diff?src=pr&el=tree#diff-bW1hY3Rpb24vZGF0YXNldHMvYmFzZS5weQ== for detail

[kennymckormick]

I think that PR is ready for merge, would you please do another check to see if there are still some problems? @dreamerlin @innerlee . I think the remaining work on HVU is just parameter tuning, the framework doesn't need to be changed.

[innerlee]

ok, will look at it tomorrow
