emp cert-attach errors with error: no stack for app found on a new app

[iserko]

If you have an extended Procfile as follows:

myapp:
  command: ./bin/web
  ports:
    - "443:8080"
  environment:
    EMPIRE_X_LOAD_BALANCER_TYPE: "alb"

and you do:

% emp create myapp
% emp deploy -a myapp myapp/myapp:latest
# the command returns an error
error: the myapp process does not have a certificate attached

If you try to do emp cert-attach -a myapp -p myapp <cert_arn> at that point you keep getting error: no stack for app found.
I checked CloudFormation and there was no stack triggered for the app.
Seems like the failed deploy still triggers something, but doesn't reset it in case of a cert failure.
Then when you try running cert-attach, it wants to do an update of the stack, but there isn't one.

Workaround: destroy the app and recreate it and this time do cert-attach before deploy
