[FIX] base: don't uninstall already uninstalled modules

Before this commit:
    - Install some random module that can be uninstalled (so not base)
    - Open the uninstall wizard for said module in two different tabs /
        windows / whatever
    - In one tab, confirm the module uninstall and wait for it to be
        done
    - As soon as the other tab is done with the uninstall, go to the
        second one with the uninstall wizard still open, and proceed
        with the second uninstall
    - Boom, the registry crashes and completely fucks up the DB because
        there's no check at all that prevents the uninstall of already
        uninstalled modules.

After this commit:
    - `ir.module.module.button_uninstall` will check if all the
        modules being uninstalled are in the installed state
        and if not a UserError will be raised, preventing a second
        uninstall of the module which could potentially break the DB

Do note that this fix is LOCAL, the problem is however more or less
global, wherever there's user-actionable buttons that should only be
pressed once there's a potential for bugs / breakage if a similar fix is
not implemented locally. Perhaps a more global fix should be implemented
eventually, but it's generally less annoying for business cases since
those probably won't break the registry, see task 1859014.
