Remove Account class from committers.py
https://bugs.webkit.org/show_bug.cgi?id=114671

Reviewed by Csaba Osztrogonác.

Account class was added to support watch list email addresses that are not associated with
a particular contributor but nobody uses these email address since Chromium port forked.

Remove it.

Also removed account_by_login from CommitterList since it was never called except its unittests.
