Crash when adding photos to the library.

It looks like this control has the same issue as the native iOS version, but I can't figure out what is causing it.

My users take lots of screenshots, and it is causing this crash.

guillermomuntaner/GMImagePicker#88

Thoughts?

Finally had time to figured this one out. In the ViewWillDisappear you are only Unregistering the Photopic early changes if the Picker is part of the Navigation stack. I changed it to always Unregister and the crash stopped happening. Not sure if this is the best way to handle it but it seems to work.

@alexrfan03 sorry for the late response... crazy busy at work... Do you have a PR with this change? I can merge it. Sounds like a good solution.

@alexrfan03 I think I just fixed this issue by pushing a fix for #31. Can you verify using version 2.2.2 of the Nuget package?

@roycornelissen, It is still now working on iPad with OS version 9.4.

@NeerajRai111 I'm having trouble reproducing this crash. Do you have a basic sample project that demonstrates the error? Can you reproduce it with the sample app in this repo too?
