[davimacedo]

Thanks for the PR. Could you please check the failing tests?

[bduyng]

@davimacedo seems like React Native tests are passed but I got these errors. Can you help me with this?

1) Parse EventuallyQueue can saveEventually
  - Error: Timeout - Async function did not complete within 20000ms (set by jasmine.DEFAULT_TIMEOUT_INTERVAL)

2) Parse EventuallyQueue can queue destroy then save
  - Error: XMLHttpRequest failed: "Unable to connect to the Parse API"
  - MongoError: server is closed
