JSDoc allow missing parameter names

[weswigham]

TypeScript Version: 2.7.0-dev.201xxxxx

Code

  /**
   * @override
   * @param {function(string)}
   */
  setNotify(notify) {
    this._notify = notify;
  }

Expected behavior:
strongly typed notify

Actual behavior:

front_end/audits2_worker/Audits2Service.js(33,31): error TS1003: Identifier expected.

(Error on the end of the @param line)

Found a few instances of this in the chrome devtools, which means this validates in the closure compiler. If the param names are missing, they should just be matched by position.
