### Current Behavior

When I m defining a queue with 30s delay (DelaySeconds)
After sending message ApproximateNumberOfMessagesDelayed is still at 0

Send a message 
Verify value of ApproximateNumberOfMessagesDelayed in the queue, expected value should be 1.
This is working with release 0.14.2

awslocal sqs create-queue  --queue-name test --attributes '{"DelaySeconds":"30","MessageRetentionPeriod":"86400","ReceiveMessageWaitTimeSeconds":"0","VisibilityTimeout":"0"}'

 awslocal sqs get-queue-attributes --attribute-names All  --queue-url http://localhost:4566/000000000000/test
 awslocal sqs send-message --queue-url http://localhost:4566/000000000000/test --message-body 'test'
 awslocal sqs get-queue-attributes --attribute-names All  --queue-url http://localhost:4566/000000000000/test
