Summary:
The icon size in the test/example cannot be rounded correctly as 3x image, causing redbox like:
```
-[RNTesterSnapshotTests testTabBarExample] : failed: caught "NSInternalInconsistencyException", "RedBox error: Error setting property 'icon' of RCTTabBarItem with tag #14: Image source flux@3x.png size {33, 33} does not match loaded image size {33.333333333333336, 33.333333333333336}."
```
This simply resizes them from 100x100 to 99x99

Summary:
We found that `-[CALayer renderInContext:]` produces bad results in some cases (which is actually documented thing!),
so we decided to replace it with `-[UIView drawViewHierarchyInRect:]` which is more reliable (I hope).
As part of this change I completly removed support of `CALayer` from local fork of `RNTesterIntegrationTests`.
See https://github.com/facebook/react-native/pull/14011#issuecomment-303844580 for more details.
