remoteUpdate === null can be due to the following reasons:
- No CodePush updates were installed since the last time disallowRestart was called, and therefore, there isn't any need to restart anyways.
- There is currently a pending CodePush update, but it was installed via InstallMode.ON_NEXT_RESUME and the app hasn't been put into the background yet, and therefore, there isn't a need to programmatically restart yet.
- The currently running app already has the latest release from the configured deployment, and therefore, doesn't need it again.
- No calls to restartApp were made since the last time disallowRestart was called.
