Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I've included a working example of the issue. In the example it will:

1. Start the localstack server
2. Bootstrap the CDK
3. Deploy the nodejs function with a version (this works fine)
4. Redeploy the nodejs function with a minor change to the handler. (this will fail)

The output from the example will provide you with all the details of the issue.

2:07:29 AM | UPDATE_FAILED | AWS::Lambda::Alias | FnAliaslive17DB7803 Resource provider operation failed: An error occurred (ResourceConflictException) when calling the CreateAlias operation: Alias already exists: arn:a ws:lambda:us-east-1:000000000000:function:AliasExampleStack-Fn9270CBC0-d1955cf2:live

Expected Behavior

The second deployment should work with the new handler.
