[ASDisplayNode] Short circuit measure calls that have a zero-area constrainedSize. (facebookarchive#1939)

* [ASDisplayNode] Short circuit measure calls that have a zero-area constrainedSize.

  // If the constrainedSize is completely zero-area, then there is no possibility for layout calculations to be successful.
  // This also avoids the issue of an inset being applied to 0, creating negative frame values.

* [ASDisplayNode] Fix to shouldMeasure change.

* One more fix.
