CreateScopeAsync not creating collections in ScopeSpec

Summary: When defining a ScopeSpec object with Collections, and then using CreateScopeAsync, the scope is created but not the collection.

Repro:

1. Create ScopeSpec with name "MyScope".
2. Add a list of CollectionSpecs to it (coll1, coll2, etc0
3. Call CreateScopeAsync with the ScopeSpec

Expected:
Scope "MyScope" should be created with with the given collections.

Actual:

Scope "MyScope" is created, with no collections.
