This side-steps a double-import problem that is triggered when we
perform an unimport in a particularly unfortunate order. (don't ask)
The root cause of the problem still exists: we can get into a situation
where a live recovery_homescreen is running from an unimported module,
meaning that any new import of anything from the recovery_device
namespace will _also_ be a double-import. We don't have a fix for that
situation yet, so instead we avoid this particular local import, which
would cause homescreen_dialog to have its own copy of the `recover`
module.
