[CT-3530] Presence of saved_queries breaks lineage viz

[dbeatty10]

Describe the bug

The lineage visualization fails to render when including saved_queries within models/_properties.yml.

Steps To Reproduce

semantic_models:
  - name: my_semantic_model
    model: ref('metricflow_time_spine')
    # model: ref('my_model')

metrics:
  - name: my_metric
    label: my_metric
    type: derived
    type_params:
      expr: revenue - cost

saved_queries:
  - name: p0_booking
    description: Booking-related metrics that are of the highest priority.
    query_params:
      metrics:
        - my_metric

dbt docs serve

Expected behavior

I expected to see the entire lineage instead of a blank lineage:
