Turn off race detection for upload test (#1082)

This patch can be reverted after the upstream testify library
fixes the code which causes a race condition when mocking.

I couldn't quite figure out how to run the single test without race detection while
running others with race detection, so I've temporarily added two test commands
in the go-ci.yml file.
