non-interactive: review_code fails to initialize ChromaStore

[nicola-mazzucato-arm]

It appears there's an issue with indexing and then review_code in for non-interactive sessions.

Sequence:

metis --codebase-path <path_to_repo> --verbose --log-level info
index

close CLI session

metis --codebase-path <path_to_repo> --verbose --log-level info -non-interactive --command review_code
ERROR - Error initializing ChromaStore: Could not connect to tenant default_tenant. Are you sure it exists?

Temporary workaround:
