[FIX] stock: clean-up sequences at uninstall

When stock is uninstalled, the sequences used in the warehouses for the
picking types are kept. However, since [1], picking types cannot be
duplicated anymore. When the module is re-installed, the picking types
are created with the same name, which is not allowed by [1].
