When quickly minimizing and restoring an app, OnApplicationPause() gets called twice in a row, followed by two resume calls.

Steps to reproduce:
1) Open the latest attached project.
2) Build for iOS.
3) Run on a device via Xcode.
4) Press the lock button on the device.
5) Quickly unlock the device and return to app.
- The issue might show up already (background turns red in the app), if not, proceed.
6) Minimize the app with the 'Home' button.
7) Tap the app icon to bring it back.
- Repeat 4-7 until the background in the app turns red.

In Xcode's console, notice the 'PAUSE CALLED TWICE' messages, they indicate that OnApplicationPause() gets called twice in a row and has the same pauseStatus (true).
