[IMP] base: use 'raise_view_error' when checking the inheritance

The message used in 'valid_inheritance' was not very helpful when the
inheritance validity was not passed.
You only knew that some view was not OK without knowing which one.

We now use the 'raise_view_error' method, which can already display all
the meaningful info (view_id, parent_id, view name, ...)
