* Fix buildExportAll to account for commonjs/amd If the re-exported module was generated with Babel and it is a commonjs or amd module and so is the current module, this will result in an attempt to redefine the __esModule property, which throws a runtime error. * Add test: don't overwrite __esModule on re-export (Failing.) * fixup tests * Add fix for systemjs
