config for ci launch_apb_on_bind = false seems to cause issues

Bug:

Note
This is currently happening on my PR not sure if it is a wider issue
#828

What happened:

Running the CI job it fails waiting for postgres to be deprovisoned. This looks to fail because are still bindings present:

172.17.0.5 - - [27/Mar/2018:08:29:22 +0000] "DELETE /ansible-service-broker/v2/service_instances/a8b175f5-37c5-4fd9-abd4-4fff930c1eb2?accepts_incomplete=true&plan_id=7f4a5e35e4af2beb70076e72fab0b7ff&service_id=1dda1477cace09730bd8ed7a6505607e HTTP/1.1" 400 3

I believe the issue here is the setting launch_apb_on_bind as this is false nothing is removing the binding reference.

My question: Is launch_apb_on_bind why do we want this to be false, is it a real scenario if so should we just remove the binding reference when this is set.

Looking more into this I think I know what the problem is and it is in my code change. But wondering what the usecase for launch_apb_on_bind=false would be?
