flatten command - prune oneOf field on circular references

[tcdsv]

issue: #465

Conditions for pruning the 'oneOf' field:

• The schema being merged is a child of another schema, through the oneOf field.
• In the unmerged schema, the parent schema is nested within the 'allOf' array, creating a circular reference
• The 'oneOf' field in both the parent and child schemas is identical.
• The parent schema contains a non-empty propertyName discriminator field
