Auto-role setting is applied even when unticked

[gmsb]

The "Auto Role Automatically give registered visitors the XYZ forum role." field is being applied even when the checkbox is un-ticked.

I was able to replicate this across dev/staging/production, the state of the checkbox was ignored in all 3 instances.

I'm not able to duplicate this on 2.6.

A few things do happen here, by design:

• On plugin activation, the user who activated bbPress is automatically made a Keymaster. This is to allow someone to actually create forums and moderate topics out of the box. This skips that setting.
• With this box checked, logged in users automatically get the default role saved in the database for that site.
• With this box unchecked, logged in users automatically receive a role based on bbp_get_user_role_map(), which maps administrator to bbp_get_keymaster_role() and everyone else to bbp_get_default_role().

Maybe we need more options here? Or an option to do nothing basically?
