CRM-21247 User Record link (in the Actions section of a contact record summary) is broken

when viewing a contact record (drupal 7.x, civi 4.7.22+) the User Record link under Actions has the cid appended to the end causing it to break.

I've looked around and can not figure out why the cid is being appended

in CRM/Utils/System/DrupalBase.php
this formats the link
  public function getUserRecordUrl($contactID) {
    $uid = CRM_Core_BAO_UFMatch::getUFId($contactID);
    if (CRM_Core_Session::singleton()
        ->get('userID') == $contactID || CRM_Core_Permission::checkAnyPerm(array(
          'cms:administer users',
          'cms:view user account',
        ))
    ) {
      return $this->url('user/' . $uid);
    };
  }

a temp fix is to add a slash after the uid which causes the system to ignore the cid
      return $this->url('user/' . $uid."/");
