Remove verification of PRE_ON_CREATE

It was migrated from androidx.test.runner.lifecycle.Stage, which is
only dispatched from androidx.test.runner.MonitoringInstrumentation.

Since the tests use self-defined LifecycleLog.ActivityCallback,
the PRE_ON_CREATE always appears with ON_CREATE. So now it becomes
redundant.
