provider returns error for app creation but create app in UI

[Josh-Tracy]

Issue

When I create a fortanix app using the dsm provider I get the error:

CAll DSM provider API returned non-JSON API: GET sys/v1/apps/<app_id> 401: This operation requires an account to be selected first

HOWEVER the app is created and appears in Fortanix.

Steps to reproduce

Create a dsm_app using this code

resource "dsm_app" "app" {
  name = "testApp"
  default_group = module.dsm_group.group_id
  other_group = []
  other_group_permissions = {}
  new_credential = false
}

Expected Outcome

Terraform apply to return no errors and show app created when app is created in Fortanix.
