Clear list rings when loading a new formspec

Fixes a bug where the old list ring remained when a new formspec
was displayed over the old one. This created the list-ring of the new formspec
to be partly ignored.

Thanks to @VanessaE to report the bug, and @DonBatman to produce the code that
exposed it.
