Description

When opening and closing the camera plugin without taking an image, the memory allocated under 'Other Resources' grows without ever being cleaned up.

Testing on an iPad mini 1, when I open and close the camera plugin without taking a picture I can crash the app. This usually takes about 130-150 times opening and closing the camera to cause a crash. The leak is present on newer devices but the app is harder to crash due to the much larger device memory.

Steps to reproduce:
1. create an app with the camera plugin
2. run the app on an iPad mini 1
3. open the camera plugin to take a picture, not from the gallery
4. click cancel
5. repeat 3 + 4 until the app crashes

It appears that Jetsam kills the app for not being a good memory citizen.

EDIT: I've tested this further and it appears on my iPad mini 3 as well although it's harder to trigger. I've included a sample app that can be used to view the problem

By clicking the 'trigger camera' button and then clicking cancel and repeating the process you can see that while the app memory usage stays steady, the other processes accumulate memory.
