Hah, James commented in my earlier CL
(https://chromiumcodereview.appspot.com/461273003/) that we shouldn't need this
for all tests, so ideally it should be defined only for those that need it. But
I remember there are likely to be startup ordering issues that prevent that.

 
   // Register the chrome-extension:// scheme via this circuitous path. Note
   // that this does not persistently set up a ContentClient; individual tests
