Initial b6ed34e1 idea was to ensure that we always have
_rewrite_len and _routing_map defined. Unfortunately, this
is not correct since class attribute defined dynamically
are actually added in registry, and recomputed on each install.
More than that, the call si shared between multiple database
meaning that routing_map cache may be shared between multiple
database whcich is not correct.
After b6ed34e1, when installing discuss on a fresh database without
demo, all discuss routes will be unknown since None is already in
_routing_map and thus routing_map is not recomputed.
When routing_map is on the model class, in registry,
a new install will reset the class, remove the _routing_map attribute,
which will fix the problem.
