Description:
User configured experimental features, such as Navigable Table of Contents and Dialogues need to be turned off, if a user leaves the usability beta.

For Firefox 3/3.5 users, if a user leaves the beta, the classic toolbar in monobook disappears as NTOC is remained turned on.

The problem could not be reproduced in IE or Opera.

Steps to produce:

1. Create a new account (to have fresh default preferences)
2. Opt-in to the beta
3. Turn-on NTOC and Dialogues from Preferences (Experimental features under "Edit")
4. Opt out from the beta
5. Open edit tab
6. NTOC is visible and classic toolbar is gone.

Expected behavior:
When a user opt-out from the beta, all experimental features need to be turned off.
