fix: handle missing RESOURCE_SERVICE_PATH in sync task (ansible#624)

There is an error in eda-server when running the periodic task to sync
shared resources:
```
default-worker.log:Sep 20 18:52:40 ip-10-0-14-133 automation-eda-controller-worker-0[86746]: 2024-09-20 18:52:40,887 aap_eda.tasks.shared_resources ERROR    Failed to sync shared resources. Error: get_resource_server_client() missing 1 required positional argument: 'service_path'
```

That is solved by @AlanCoding through
ansible/eda-server#1059
Here I just handle the error for the absence of the mandatory param in
`get_resource_server_client`. According to the code, this param can not
be empty. I wonder if this eventuality should be handled in the
constructor:
