Some options not written to trac.ini when AccountManagerPlugin is installed

[Ryan J Ollos]

This issue reminds me of #11520.

To reproduce, create environments before and after installing AccountManager:

$ virtualenv pve
$ . pve/bin/activate
$ pip install svn+https://svn.edgewall.org/repos/trac/trunk
$ trac-admin trac1 initenv "project" sqlite:db/trac.db
$ pip install svn+https://trac-hacks.org/svn/accountmanagerplugin/trunk
$ trac-admin trac2 initenv "project" sqlite:db/trac.db
$ diff trac1/conf/trac.ini trac2/conf/trac.ini

Here is the diff:

The options that are redefined on acct_mgr.web_ui.LoginModule are missing from trac.ini: ​browser:accountmanagerplugin/trunk/acct_mgr/web_ui.py@15454:315,319,323,332#L305.

Also, an Option that is defined on acct_mgr.notification.AccountChangeNotification is mysteriously present. The Option instance is defined on a class that doesn't inherit from Component: ​browser:accountmanagerplugin/trunk/acct_mgr/notification.py@15454:70#L67.
