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

…ox (facebook#41686)

Summary:
X-link: facebook/yoga#1485


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
