fix(ios): only check permission descriptions availability in debug bu…

…ild (react-native-camera#2070), Fixes react-native-camera#2069

It seems like Apple is rejecting apps that access a Info.plist usage description that is not available. This conflicts with enhanced developer warnings I implemented in react-native-camera#2048.

To fix that I changed the implementation to only check if the usage descriptions are available in `DEBUG` mode. I also added a note developer warnings, that the app might crash in release mode because using a feature that requires a usage description without having one provided will result in an application crash).
