Fix issue where percentages were off of the border box, not padding b…

…ox (facebook#1485) Summary: Pull Request resolved: facebook#1485 X-link: facebook/react-native#41686 The size of the containing block is the size of the padding box of the containing node for absolute nodes. We were looking at `containingNode->getLayout().measuredDimension(Dimension::Width)` which is the border box. So we need to subtract the border from this. Added a test that was failing before this change as well Differential Revision: https://www.internalfb.com/diff/D51330526?entry_point=27 fbshipit-source-id: eb59fcfcdd6ee40674d5286f1f24426283c92e39
