[FIX] registry: init_models() using a closed cursor

When a call to init_models() fails, the post-init queue still contains
callables that refer to a soon-to-be-closed cursor.  If one calls
init_models() in another request, the post-init process will inevitably
fail because it refers to closed cursors.
