Two new Exceptions are now thrown when routing does not
work, one being thrown when a URL is generated but could
not be generated, and one when a URL could not be resolved.

This is much cleaner than the distinction of a nullable return type,
so the new interface is adapted as well.

As a drive-by fix, the Backend routing exception now inherits from
this new exception.
