Unable to create application

Description

Ran sunbeam on single node [1] and got an error in terraform plan that deploys openstack cloud [2]

The terraform logs shows the following error:

There are 2 instances of traefik charm deployed with different app names. This is intermittent and happens rarely but seems like there is race either in terraform-juju-provider or juju.

terraform provider version used: 0.11.0 juju version used: 3.4/stable (3.4.1 at the time this bug is observed)

TF provider 0.11.0 is using a different deploy code path with juju >= 3.3 than juju < 3.3. This is most likely a juju bug, not terraform provider.

Added a simple terraform plan with 2 traefik instances

This already happened in terraform provider < 0.11
