As part of SERVER-86057 a lot of get_executor logic is moved into query_planner_params as well as the interface has been changed.

Due to interface changes, existing index filters unit tests fail. More precisely mocked collection does not have shared decorators being initialized and this is where the index filters (old query settings mechanism, not the new one introduced in PM-412) are stored.

In order to speed up the work on query settings application for agg, the work for fixing these tests are planned as part of this ticket
