Summary: Fixes T54997838 by preventing any view mutations during `onMeasure` calls. There might still be places where this is possible, but this is where I'm seeing all the crashes currently. See comments in ReactRootView for why views were mutated during onMeasure. Changelog: [Internal] Reviewed By: mdvacca Differential Revision: D18518591 fbshipit-source-id: 1406af8a6b0bfcc86f4cc5b451b3967f312dfd85
