Mike Samuel e07c4b2ea1 Add polygerrit-ui/app/test/common-test-setup.html
This is a partial roll-forward of c/106190

This replaces all loads of iron-test-helpers with a load of a file
that wraps it, and adds that file to test files that do not currently
load iron-test-helpers.

A future CL will also install polymer-resin via common-test-helpers.html.

I tested by running

$ WCT_ARGS="-l chrome" ./polygerrit-ui/app/run_test.sh
