LayoutInstance.query_layout_obj_instances misses one object on Linux

### 🐞 Description of the bug

Calling `LayoutInstance.query_layout_obj_instances` on Linux results in one object always being left off the end of the list as demonstrated by the test added in https://github.com/ansys/pyedb-core/tree/qloi-bug-example.

The output of the steps below points to this check in `LayoutInstance.query_layout_obj_instances.process_hits` as the culprit:

https://github.com/ansys/pyedb-core/blob/847eb09cba2278f0c169119aa30ee1b9d5296fc3/src/ansys/edb/core/layout_instance/layout_instance.py#L101-L103

When the result is not streamed (as done in this version on Linux due to a server-side issue), the last `hit` pulled from the iterator has `is_end_of_query_results_group==True` which causes the processing of the hit to be skipped even though it contains an `edb_obj` message that should be added to the returned list.

### 📝 Steps to reproduce

1. Check out https://github.com/ansys/pyedb-core/tree/qloi-bug-example
2. Install:
```
[uv] pip install -U -e .[tests]
```
3. Run the test:
```
pytest -v tests/e2e/unit_tests/test_layout_instance.py::test_layout_instance_smoke
```

Output:

Start in src/ansys/edb/core/layout_instance/layout_instance.py at LayoutInstance.query_layout_obj_instances.process_hits, then run tests/e2e/unit_tests/test_layout_instance.py::test_layout_instance_smoke on Linux. Confirm that the hit containing edb_obj id 24 is included in the returned objects, with the test expecting three objects instead of two.
