New description:
#29642 added checks for the signatures of custom error handlers.
When the 'path.to.view' cannot be imported, it raises ModuleNotFoundError
or ViewDoesNotExist, as seen in this Stack Overflow question:
https://stackoverflow.com/q/55481810/113962
I suggest we catch the exception, and add another check code, e.g.
{{{
* **urls.E008**: The custom ``handlerXXX`` view ``'path.to.view'`` cannot
be imported.
}}}
