Keda: Keda keeps managing deleted ScaledJobs

[OrenLederman]

The Keda operator logs still show that it's querying the queues after the ScaledJob is deleted. I believe it also tries to instantiate Jobs (and fails) if there are work items in the queue. I used it with a GCP PubSub scaler

Workaround - restart the operator

Expected Behavior

Keda should identify deleted ScaledJobs and stop querying their queue

Actual Behavior

Keda keeps querying delete jobs' queues.

Steps to Reproduce the Problem

1. Create a ScaledJob (with a GCP PubSub trigger)
2. Verify that Keda identified the job and it querying the eueue
3. Delete ScaledJob
4. Check the Keda operator log

Specifications

• **KEDA Version: 2.0.0-RC
• **Platform & Version: Ubuntu 18 and GCP's Container Optimized OS
• **Kubernetes Version: v1.16.13-gke.401
• **Scaler(s): gcp-pubsub

Thank you guys.
It seems an issue of the ScaledJob finalizer. I'll try to repro it.
I'm pretty busy for a couple of days, however, after that, I'll do it.

@TsuyoshiUshio I can take a look on this one.
