Move the fake entry points of RootFlowNodeTest to the test modules

The fakes were declared in RootFlowNodeTest, so other tests could not use
them. Move each of them next to the API it fakes, following the existing
convention of a createNodeResult lambda defaulting to lambdaError():

- FakeLoginEntryPoint in features/login/test
- FakeBugReportEntryPoint in features/rageshake/test
- FakeSignedOutEntryPoint in features/signedout/test (new module)
- FakeAccountSelectEntryPoint in libraries/accountselect/test (new module)

The login and rageshake test modules did not have Appyx on their
classpath, so add the architecture module to their dependencies.
