Naming: should all of the indentifiers s/Test/Fake/ for clarity?

(In general I think it's better to reserve 'Test' for the names of test
fixtures, and to clarify whether test object are fakes, mocks, or stubs)

We have bunch of existing fakes prefixed as Test, so I think if we fix them we
should fix them altogether as a separate effort. Filed crbug.com/688063 to
address that.
