Not able to bind secrets (that are not associated with app anymore) to another app.

[sangee2004]

Acorn version - v0.6.0-143-g94d09a10+94d09a10

Steps to reproduce the problem:

1. Deploy an app which has secrets.

args: password: ""

containers: app: {
  image: "nginx"
  env: {
    PASSWORD: "secret://user-password/password"
  }
  ports: publish: "80/http"
  files: {
      "/usr/share/nginx/html/secret.html": "secret://user-password/password"
  }
}

secrets: "user-password": {
  type: "opaque"
  data: password: "\(args.password)"
}

2. Once app is deployed successfully , delete this app without deleting secrets.

3. Deploy another app by binding the secrets (relating to the deleted app) . App deployment is in "pending" state with error - [secrets: missing: [mytestsec]] message

containers: {
  nginx1: {
    image: "nginx"
    ports: publish: "80/http"
    files: {
      "/usr/share/nginx/html/secret.html": "secret://user-password/password"
    }
}
}

 % acorn rm mytestsec                                                                  
Removed: mytestsec
% acorn run -n mytestsecbind1 -s mytestsec.user-password:user-password -f AcornfileBind

Tested with acorn version v0.8.0-alpha7-143-g86de32e8+86de32e8

1. Deploy an app which has secrets.
2. Once app is deployed successfully , delete this app without deleting secrets.
3. Deploy another app by binding the existing secret (which was created as part of app deployment in step1).
   App deployment succeeds and app get access to the existing secret as expected.
