[5.0.x] Fixed #34975 -- Fixed crash of conditional aggregate() over aggregations.

Adjustments made to solve_lookup_type to defer the resolving of
references for summarized aggregates failed to account for similar
requirements for lookup values which can also reference annotations
through Aggregate.filter.

Regression in b181cae2e3.

Refs #25307.

Thanks Sergey Nesterenko for the report.
