Invariant Violation: "main" has not been registered. This can happen if:

* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.

* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called.
