Feature: trace with warning for stylesheets without dynamic values

[bobbyjcolley]

Hi React Native Dynamic!

I've recently just migrated a large React Native application using react-native-dynamic and we had about 70 files which have not used any dynamic values. Lots of console.warns in our console now!

Can we display a stack trace so the developer can swap it out?

Let me try adding a console.trace() here!
