Plugins: Clean up `uninstall_plugins` option during database upgrade. 

`register_uninstall_hook()` is designed to be given a function callback (or a static class variable), not an array/object instance. This got blocked in [16339] but the option itself was never cleaned up.

Props polevaultweb.
Fixes #31625.
