[FIX] base: remove copied views before uninstall

In dff64b6 some copied views with no link to a module would be
removed after module uninstall.

But this has some side effects when the website module is being removed.

For example:

- website_theme_install, website are installed
- website is uninstalled (which will uninstall website_theme_install)
- website.theme_customize view can't be removed because it is used by
  copied view website_theme_install.customize_modal
- after uninstall _remove_copied_views will remove the view
  website.theme_customize but when trying to remove associated
  website.page will throw an error because website_page table does not
  exist

This issue does not happen if we uninstall first website_theme_install
then website (since like this the reference is not an issue).

The issue also happen with overriding views in theme_bootstrap and
possibly elsewhere.

With this changeset, copied views are removed before uninstalling module
data.
