Error during service upload

[Sergey Murashov]

Steps to reproduce:
1. Check that old cache is deleted.
2. Restart murano-repository
3. Send PUT request with the following body: {"name": "test", "version": "0.1", "full_service_name": "test", "service_display_name": "test"} to http://<url>:8084/v1/admin/services/test

Actual result:
We get 500 error status code and the following traceback in murano repository logs:
