launchApplicationOnPush can be false

If launchApplicationOnPush is false, the if check will not allow pushServiceObj.launchApplicationOnPush(false, function to run.

Therefore, we don't need to check anymore.
Ah, new pull request. I was just suggesting this in the other pull.

`Hmm, technically we don't need to call the launchApplicationOnPush [false] function if it's false, since it defaults to false. We could however still call it if you wish. I would suggest removing the if all together if you wanted to do that, since launchApplicationOnPush will never actually be undefined, with my recent change.`
