Answer form still appears once an answer has been submitted

In Version 7.x-2.0-rc3+6-dev

Answering form was still visible for users already submitted votes because submitted state was computed wrong.

Original line 845:
$submitted = user_is_logged_in() && in_array($user->uid, array_keys($uids));
Patched line:
$submitted = user_is_logged_in() && in_array($user->uid, array_values($uids));

Please test and include patched line in future releases.
