LocalStack v0.10.8 fails to retrieve the CloudFormation stack after it successfully deployed the stack. The DEBUG output shows LS creating the CFN stack. The CFN template creates an IAM::Role. But then LS fails with "Unable to extract id" and then LS fails with a ValidationError. LocalStack correctly created the IAM::Role and the command-line "aws --endpoint... cloudformation list-roles" returns the role.

It looks like there's a bug in cloudformation_starter.py:299 where it's looking for a lower-case "id" but the next line parses "RoleId" from the response. The absence of "id" causes the error "Unable to extract id for resource" on line 307. 

Here's the response that LS expects to find an "id". (Sorry about the terrible formatting)

```
