When the user doesn't have permissions (for instance content/read) then eZ\Publish\Core\Base\Exceptions\UnauthorizedException is thrown.

Behavior in v1 and legacy
A user is redirected to the login page (by default /login).

Current behavior
A user is not redirected. An application shows

The server returned a "500 Internal Server Error".

In the logs are entries regarding that:

request.CRITICAL: Uncaught PHP Exception Twig_Error_Runtime: "An exception has been thrown during the rendering of a template ("User does not have access to 'read' 'content'")." at /Users/kamil/www/ezplatform-ee/vendor/ezsystems/ezpublish-kernel/eZ/Bundle/EzPublishCoreBundle/Resources/views/pagelayout.html.twig line 11

Unknown macro: {"exception"}

Expected behavior
As in v1 and legacy.
