Occasionally doesn't show my full streak stats, just truncated ones

**Describe the bug**

Occasionally when I view my profile, the streak stats only go back to Feb 2016. Usually it's correct and shows back to 2014, but every so often I see it truncated.

**To Reproduce**
Steps to reproduce the behavior:

1. Go to https://github.com/unixorn?tab=overview&from=2014-12-01&to=2014-12-31
2. View the inline streak stats chart

Unfortunately it's intermittent, that will usually show the correct stats, it's only occasionally truncated.

**Expected behavior**

I expect it to always show the same correct stats
