Looking at this here, I'm pretty sure that we *don't* want to import
testharnessreport.js if it's modified, since that will overwrite our own custom
version of testharnessreport.js.

[jsbell, 2016/09/01 16:51:05]

We *always* want to use "our" copy of testharnessreport.js - the one in wpt is
useless to us.

I thought we'd settled on using the upstream (wpt) version of the other files.
This method is "_copy_resources_to_wpt" so I assume it's copying e.g.
resources/testharness.js to imported/wpt/resources/testharness.js - which seems
backwards to me.

Is the function name incorrect? Or am I very confused?
