Ti.TouchID causes a crash on Android devices that don't support fingerprint authentication, or where any fingerprint hasn't been added yet.
In such devices, the constructor for FingerPrintHelper throws an exception, and every subsequent reference to the object triggers an error of this kind:
Steps to reproduce:
- Create a Titanium app that requires ti.touchid
- Install on a Android device with no fingerprint added by the user
- Call any method of ti.touchid
