Refactor ParseQueryControllerTests and add new tests

Updated `ParseQueryControllerTests` to remove `mockDecoder` in favor of `serviceHub.Decoder`, with corresponding changes to the setup method and test assertions. Removed several test methods for simplification.

Deleted `ParseQueryExtensionsTests` as part of consolidation of tests.

Introduced `ParseQueryTests` with comprehensive tests for the `ParseQuery` class, covering various query methods and ensuring proper interaction with `IServiceHub`. This enhances the overall test coverage.
