IdentityTestEnvironment's method casts the PO2TS to a FakePO2TS
but do not enforce this at compilation (in order to support
IdentityTestEnvironmentProfileAdaptor).

Add a DCHECK in IdentityTestEnvironment::Initialize() to check
that the PO2TS is a FakeProfileOAuth2TokenService (required to
add a new virtual method to determine this as Chromium builds
without RTTI).
