Commit 5a81d8883 fixed the COW view deletion on module update but introduced an
error when installing a theme.

Indeed, when installing a theme, the first step is to remove the currently
installed theme from the website (by unlinking its ir.ui.view).

Commit 5a81d8883 introduced the fact that deleting an ir.ui.view during a

`_get_specific_views` (that expects a singleton).

When installing a theme, it calls `_theme_cleanup` which search COW views and
unlink them. If not cow view, unlink is called with an empty record set raising
the singleton error.
