Fix caching for CI/CD tests

[PhilippRue]

The caching for a simple VoronoiCalculation (and probably also other calculations and workflows) does not work anymore:

Description of the symptoms

$ pytest calculations/test_vorocalc.py -svx
...
calculations/test_vorocalc.py::test_voronoi_cached /opt/aiida-kkr/tests/jukkr
...
out, node: {'remote_folder': <RemoteData: uuid: 4852c1b1-78e2-4bc3-99c0-9ec38ed18577 (pk: 16)>, 'retrieved': <FolderData: uuid: 750d76e5-d743-4646-a718-2feace95878d (pk: 17)>, 'output_parameters': <Dict: uuid: 8aceebeb-0f5b-4363-aaa0-4b74718c9d1a (pk: 18)>} uuid: 6a820659-6ca3-4d7c-887a-eb54f487e037 (pk: 15) (aiida.calculations:kkr.voro)

ignored attributes: ('metadata_inputs', 'queue_name', 'account', 'qos', 'priority', 'max_wallclock_seconds', 'max_memory_kb', 'version', 'version', 'environment_variables_double_quotes')

Rerunning it produces different hash values for the calculation, although the inputs for the hash are identical (same hash also for structure and parameters). The only difference is in the code hash, which should, however, not be used at all.

Used Python and AiiDA environment

• Ran on iffaiida image.
• AiiDA v2.6.3
• Python 3.12.7
• Installed aiida-related packages:
