Rudimentary tests for not covered entry points (facebook#11835)

* Add basic snapshot tests to ReactART components (Circle, Rectangle, Wedge)

* More tests on Circle, Rectangle, Wedge

* linc warning fixes

* - remove tests to Wedge component internal function

* More test on Wedge component, update snapshots
