Fix handling of creating an Access Policy for a non-existent Key Vault

[jen20]

This pull request adds an acceptance test demonstrating the case where a key vault access policy resource is created with a bad key vault ID. Currently, the Terraform CLI gives the following output for this configuration:

resource "azurerm_key_vault_access_policy" "policy" {
  # This ID shouldn't exist but must be in the URI-style format with enough components
  key_vault_id = "/subscriptions/redacted/resourceGroups/myrg/providers/Microsoft.KeyVault/vaults/idontexist"

  tenant_id = "00000000-0000-0000-0000-000000000000"
  object_id = "11111111-1111-1111-1111-111111111111"

  key_permissions = [
    "get",
  ]

  secret_permissions = [
    "get",
  ]
}

$ terraform apply                                                                                                                                               ⇡ master :: 19h :: ⬡

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  + azurerm_key_vault_access_policy.policy
      id:                   <computed>
      key_permissions.#:    "1"
      key_permissions.0:    "get"
      key_vault_id:         "/subscriptions/redacted/resourceGroups/myrg/providers/Microsoft.KeyVault/vaults/idontexist"
      object_id:            "11111111-1111-1111-1111-111111111111"
      resource_group_name:  <computed>
      secret_permissions.#: "1"
      secret_permissions.0: "get"
      tenant_id:            "00000000-0000-0000-0000-000000000000"
      vault_name:           <computed>

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

However, state shows:

{
    "version": 3,
    "terraform_version": "0.11.11",
    "serial": 1,
    "lineage": "74a73fbb-d75a-af7a-c1dc-6d73cc1e9a73",
    "modules": [
        {
            "path": [
                "root"
            ],
            "outputs": {},
            "resources": {},
            "depends_on": []
        }
    ]
}

The test reproduces this workflow, and the subsequent commit makes it pass by removing the branch at which a nil state and nil error is returned during creation.

Hi @jen20,

Thank you for the bugfix. While this works great on creation, on update we still need to check for a not found response as the keyvault the policy was created with no longer exists (and thus by proxy the resource has been deleted)

This will also need to be done for the other key vault resources but i'll open a PR for that.

Thanks @katbyte - after e99279b, the related tests all run OK:
