Environments with a domain cannot be initialized after v0.6.0

[efekarakus]

Description

After upgrading to v0.6.0, I initialized an application with the domain name flag:

$ copilot app init --domain domain.com

And then I tried to create an environment with the default VPC configuration:

$ copilot env init

However, I received the following error:

✘ Failed to accept changes for the test environment.

✘ check if changeset is empty: create change set copilot-3eebf082-52de-4746-8344-b4494b067bae for stack nginx-app-test: ValidationError: Template format error: Unresolved resource dependencies [PublicLoadBalancer, DefaultHTTPTargetGroup] in the Resources block of the template
	status code: 400, request id: 22d3d606-56b0-424c-9b72-c7fc2d291f64: describe change set copilot-3eebf082-52de-4746-8344-b4494b067bae for stack nginx-app-test: ValidationError: Stack [nginx-app-test] does not exist
	status code: 400, request id: 6020e4b2-9c4a-4ae0-892e-36e3cf7bbad8

Why?

I believe this is happening because of the following resource:

copilot-cli/templates/environment/versions/cf-v1.0.0.yml

Lines 161 to 165 in c47e17b

	HTTPSListener:
	Type: AWS::ElasticLoadBalancingV2::Listener
	DependsOn: HTTPSCert
	Condition: DelegateDNS
	Properties:

The ALB does not exist by default anymore and the DelegateDNS condition evaluates to true trying to create an HTTPSListener:

copilot-cli/templates/environment/versions/cf-v1.0.0.yml

Lines 31 to 32 in c47e17b

	DelegateDNS:
	!Not [!Equals [ !Ref AppDNSName, "" ]]

Possible fixes

One way of fixing this issue is to limit the HTTPSListenerRule creation if DelegateDNS and CreateALB evaluates to true.
