tfci does not handle working directory with more than 1 level

Hello,
I am currently facing an issue with tfci running in github actions.
I setup my Terraform cloud workspace directory to be `layer0/infrastructure/eks`
But tfci 1.3.0 command:
```
tfci -hostname= -token= -organization= run create -workspace=myworkspace -configuration_version=cv-xxxxxx -message= -plan-o
nly=true
```
returns
```
lstat /home/tfc-agent/.tfc-agent/component/terraform/runs/run-o2Mn1KYJt4F6TbGD/config/layer0
```

Only the root level of the working directory has been used.
If I trigger a run manually in Terraform cloud UI, no issue.

Full log:
```
tfci -hostname= -token= -organization= run create -workspace=pierre-eks-us-east-2 -configuration_version=cv-xxxx -message= -plan-o
nly=true
Created Run ID: "run-o2Mn1KYJt4F6TbGD"

Error: No Terraform configuration files found in working directory

Terraform requires configuration files to plan changes. Planning without a
configuration would mark everything for destruction, which is normally not what
is desired. If you would like to destroy everything, queue a destroy plan
instead. Otherwise, create a Terraform configuration file (.tf file), or check
that the working directory is set correctly on the workspace, and try again.
Operation failed: failed checking for terraform files: lstat /home/tfc-agent/.tfc-agent/component/terraform/runs/run-o2Mn1KYJt4F6TbGD/config/layer0: no such file or directory
```

Any idea?
Thanks.
