Prevent creation of zero-sized proxies

This wasn't seen locally b.c. it is an assert and I only ran release locally and the CQ also only runs release.

I have added linux_trusty_blink_dbg as a try job.

Since Robert is fixing the Skia code to prevent creation of zero-sized canvas, the tests should be passed now after the next Skia roll. Passing this issue to him to monitor the progress.

Removing Sheriff-Chromium as it's no longer an issue on the waterfall. I would be tempted to mark the bug as fixed as well, but I leave that to you.
