clang-format: [JS] Properly set scopes inside template strings.

Before:
  var f = `aaaaaaaaaaaaa:${aaaaaaa
              .aaaaa} aaaaaaaa
           aaaaaaaaaaaaa:${aaaaaaa.aaaaa} aaaaaaaa`;

After:
  var f = `aaaaaaaaaaaaa:${aaaaaaa.aaaaa} aaaaaaaa
           aaaaaaaaaaaaa:${aaaaaaa.aaaaa} aaaaaaaa`;
