fixes #377: Remove erroneous index confirmation message

The archiving settings page on the admin console erroneously displays "Search Indexes are rebuilding." all the time - even when message archiving isn't even enabled.

I'm actually unsure why this change works. I assume there's javascript/CSS magic that causes the problem.
