Incorrect param tags due to trailing commas

[cdtinney]

Trailing commas in a destructured object parameter result in an extra @param tag being added.

Expected Behavior

foo({
  bar,
}) {
  // stuff
}

becomes:

/**
 * [foo description]
 *
 * @param  {[type]} options.bar [description]
 * @return {[type]} [description]
 */
foo({
  bar,
}) {
  // stuff
}

Current Behavior

foo({
  bar,
}) {
  // stuff
}

becomes:

/**
 * [foo description]
 *
 * @param  {[type]} options.bar [description]
 * @param  {[type]} options. [description]
 * @return {[type]} [description]
 */
foo({
  bar,
}) {
  // stuff
}
