vmware_guest/test: create test vm in correct directory

Ensure we already create the `test_vm3` VM in the `{{ f0 }}` directory.
This to be sure the teardown playbook will be able to clean it up at the
end. This to avoid problem like this one:

```
Multiple virtual machines with same name [test_vm3] found, Folder value is a required parameter to find uniqueness of the virtual machine
```
