[Telemetry] Remove results param in shared_state.TearDownState().

[Telemetry] Remove results param in shared_state.TearDownState().

The results param was needed in shared_state.TearDownState() because of
page_test.DidRunTest hook. Now that hook is removed, we no longer need to
provide access to the results object in this method.
