### Is there an existing issue for this?

### Current Behavior

I have localstack+terraform running in our CI system that creates several SQS queues, SNS topics, and subscribing the SQS queues to the SNS topics.

Intermittently but frequently (about 35% of the time), this fails with the log message:

```
error waiting for SNS Topic Subscription (arn:aws:sns:us-east-1:000000000000:xometry-app-partner-registration:0e2fde2b-34af-49ad-812b-8fff16b63790) confirmation: timeout while waiting for state to become 'false' (last state: 'true', timeout: 2m0s)
```

I turned on DEBUG within localstack and dug this back to the following error/stack:

```
KeyError: 'Token'
  if v["Token"] == token and v["TopicArn"] == topic_arn:
File "/opt/code/localstack/localstack/services/sns/provider.py", line 517, in confirm_subscription
  self.confirm_subscription(context, topic_arn, subscription_token)
File "/opt/code/localstack/localstack/services/sns/provider.py", line 787, in subscribe
  return self.fn(*args, **kwargs)
File "/opt/code/localstack/localstack/aws/skeleton.py", line 117, in __call__
  result = handler(context, instance) or {}
File "/opt/code/localstack/localstack/aws/skeleton.py", line 165, in dispatch_request
  return self.dispatch_request(context, instance)
File "/opt/code/localstack/localstack/aws/skeleton.py", line 153, in invoke
  skeleton_response = self.skeleton.invoke(context)
File "/opt/code/localstack/localstack/aws/handlers/service.py", line 91, in __call__
  handler(chain, context, response)
File "/opt/code/localstack/localstack/aws/handlers/service.py", line 121, in __call__
  handler(self, self.context, response)
File "/opt/code/localstack/localstack/aws/chain.py", line 57, in handle
  Traceback (most recent call last):
```


### Expected Behavior

Heh, I expect the subscription to work without an error stack.

Or... if the failure is expected, for the API call to fail with an appropriate error message so I can retry.

### How are you starting LocalStack?

Custom (please describe below)

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)

I'm using the localstack helm chart.

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

`terraform init && terraform apply -var "localstack_url=http://localstack.$KUBE_NS:4566" -auto-approve`


### Environment

```markdown
- OS: Kube cluster, Linux-based x86-64
- LocalStack: installed via helm chart, version 1.0.4 from docker hub
```


### Anything else?

The terraform workspace that reproduces the problem is attached... I don't know whether we could reduce the problem by reducing the number of topics/queues being created.
