CreateComponentSnapshot broken on iOS 12


Hey @t0m, rather than hijack that other thread about Juce::Image and iOS 12, I am starting a fresh one for the createComponentSnapshot being broken.

try it for iPhone X 11.4 first
then try for iPhone XR 12.1.

Crashes with juce::Image / CoreGraphics / iOS 12

It would be better to keep everything in the same place for once - this behaviour is caused by the same issue.
