Title:
  REST API Exception during the deletion of environment

Status in Murano Project:
  Fix Committed

Bug description:
  Note:
  it is regression issue, commit 026d49b1ba60d148dcf1b81e4bc1f36129b1261e works fine, but the next commit is broken.

  Steps To Reproduce:
  1. Git checkout the master branch
  2. run REST API service in virtual environment (option, reproduced without venv too).
  3. Login via WEB UI and try to delete environment.

  Observed Result:
  Error on page with status 500.
  We can see the following traceback in horizon logs:
