Summary: Disabled producing inline source maps for debug builds. Source maps are already writte to "map" files, so this does not make sense to also inline them to the js bundle. Passing "sourceMapUrl" parameter to Metro fixed this. Reviewed By: mweststrate Differential Revision: D22159501 fbshipit-source-id: f06225cd43f44a7f93afcc32bb0501323b35d0c3
