Deleting one of the stages having a custom domain, incorrectly deletes the custom domain

[tfotis]

Consider the following configuration

{
  "version": "2.0",
  "app_name": "Hello",
  "api_gateway_endpoint_type": "REGIONAL",
  "stages": {
    "v1": {
      "api_gateway_stage": "v1",
      "api_gateway_custom_domain": {
        "domain_name": "hello.example.com",
        "certificate_arn": "arn:aws:acm:xxx",
        "url_prefix": "v1"
      }
    },
    "v2": {
      "api_gateway_stage": "v2",
      "api_gateway_custom_domain": {
        "domain_name": "hello.example.com",
        "certificate_arn": "arn:aws:acm:xxx",
        "url_prefix": "v2"
      }
    }
  }
}

The above configuration is used to create two versions of the API under the same domain, as described in this issue.

Deploy the two versions

chalice deploy --stage v1
chalice deploy --stage v2

Delete v2

chalice delete --stage v2
Deleting custom domain name: api_gateway_custom_domain

This results in deleting the custom domain entirely from API Gateway service, causing issues with all the other existing stages (e.g v1 in the example above)
