clang-format: [JS] Fix incorrect line break leading to semicolon insertion.

clang-format only works for JavaScript code, if all the semicolons are
present anyway, so this linebreak can never be desired.

Before (with appropriate statement lengths or column limit):
  return
      [ aaa ];

After:
  return [
    aaaa
  ];
