Stop quantum agents (not quantum-api) and openvswitch service. Delete
/etc/openvswitch/conf.db and delte all agents using quantum agent-delete
<id>. Start openvswitch service and then quantum agents. If ports still
down check quantum logs mainly quantum l3-agent. If you don't find anything
interesting delete the networks and recreate them.

If you still have references to "test1-int" check the quantum database
ovs_tunnel_endpoints
table and manually remove any reference.
