What existing problem does the pull request solve?

ViewManagersPropertyCache, ViewManagerPropertyUpdater static field not release when ReactInstanceManager called destroy.

I use this url to integrate RN:
[http://facebook.github.io/react-native/docs/integration-with-existing-apps.html](http://facebook.github.io/react-native/docs/integration-with-existing-apps.html)
and in Activity's onDestroy function add the follow code to release RN:
```java
mReactInstanceManager.destroy();
mReactInstanceManager = null;
```
and then when I exit activity, find the static field not release.
the follow is screen shot:
