Cannot bind to Controller lifecycle when outside of it using targetController and AutoDispose

When I'm using TargetController, Rx and AutoDisposable app fails with `io.reactivex.exceptions.OnErrorNotImplementedException: Cannot bind to Controller lifecycle when outside of it.`

Steps to reproduce:
* Open `TargetDisplayController.class` and add
```
private final LifecycleScopeProvider scopeProvider = ControllerScopeProvider.from(this);
```

* replace `onTitlePicked` with
```
@Override
public void onTitlePicked(String option) {
Observable.just(option)
.observeOn(AndroidSchedulers.mainThread())
.to(new ObservableScoper(scopeProvider))
.subscribe(new Consumer() {
@Override
public void accept(final String s) throws Exception {
selectedText = s;
setTextView();
}
});
}
```
* Pick a title and wait for logs:

Is it desired behavior? Could you suggest workarounds?

Reproduce the example in TargetDisplayController by adding ControllerScopeProvider.from(this) and using ObservableScoper, then read ControllerScopeProvider.java and the stack trace around OutsideLifecycleException. Compare the controller lifecycle state when onTitlePicked runs with the scope requirements; done means the expected behavior and a supported workaround are documented.
