In general, I'm all for sharing code. But given how little is here, I'm not
convinced this is worth the new file + new namespace.

If you convert all of the tests that need this into unit tests, you could make a
base test class that all of them derive from. I would be OK with that.

I have introduced instant_unittest_base. The InstantServiceTest and
BrowserInstantControllerTest are the subclasses.
Although BrowserWithTestWindowTest doesn't really feel like unit-test.
InstantNTPPrerendererTest can be moved on to the new InstantUnitTestBase, but
perhaps another CL.
