content_available stops sending push notification to Apple APNS silently.

[sadjow]

Describe the bug
When setting content_available in a rpush's Rpush::Apns2::Notification object. The notification is sent, but it is not displayed on the device.

To Reproduce
Steps to reproduce the behavior:

1. Create a notification object

n = Rpush::Apns2::Notification.new
n.app = my_valid_app
n.device_token = "valid token here."
n.content_available = true
n.alert = "hi!"
n.data = {
  headers: { 'apns-topic': "valid.topic.here" },
}
n.save!

3. Run 'Rpush.push`
4. The notification is delivered, but no warning is displayed, and also it is not displayed.

Expected behavior
We need to warn that the notification should not work because the content available option is not valid anymore on APNS.

I think this is related to this change #596

We just got bit by it as well when upgrading.

@thejspr yes, it was related to the content_available I had to remove it to work. I'm closing this issue.

I'm going to leave this open as a marker for the bug introduced in #596 so that others can easily find it.
