Crosperf: Fix many broken unittests.

Apparently people have been making changes and not running the
unittests; many of the unittests were suffering from bit-rot. This
CL fixes most of the broken unittests (there are still 3 large ones
being worked on -- that will be in another CL).

BUG=chromium:567883
TEST=Verified that these unittests work now.
