Deployment fails with KeyError 'table_name' (Opera v0.6.5)

When trying to deploy a ToDoListAPI example [1] with Opera v0.6.5, this results in the following error message:

opera deploy todolist_with_outputs.csar -c
Traceback (most recent call last):
  File "/usr/bin/opera", line 8, in <module>
    sys.exit(main())

  File "/home/myuser/.local/lib/python3.9/site-packages/opera/instance/base.py", line 50, in load
    self.attributes[k].load(v)
KeyError: 'table_name'

When looking at the TOSCA-model I couldn't find any obvious issues with it.

Hi @duelle does this error happen immediately after you initiate the deployment or somewhere at the middle? Currently I'm unable to reproduce this error with the CSAR above. It seems like that some attribute is unset or cannot be loaded from TOSCA.

@anzoman It occured immediately after triggering the deployment. I tried it again and it seems not to occur again. Maybe there was a side effect of a previous deployment, despite using the -c option.. Right now, the same files work for me as well..

Thanks for looking into this.
