test(dashboard): anchor the addon description test on the no-toggle branch

The test asserted that the schema description renders and that neither
piece of removed copy does, but the default renderer prints the
description too and has never carried that copy, so the assertions held
whether or not the no-toggle branch was taken: forcing hasNoToggle
false left this one green while its three siblings failed.

Assert the branch's own notice alongside the description.
