JIRA:
https://jira.appcelerator.org/browse/TIMOB-28443

Summary:

• This is a regression as of Titanium 10.0.0.
• Calling Ti.UI.ScrollView methods setZoomScale() or setContentOffset() crash with function not found.
• These methods are needed since they support a 2nd argument.

Test:

1. Build and run the code shown in TIMOB-28443 on iOS.
2. Double tap on the red square.
3. Verify that square doubles in size with an animation.
