Restarting old jobs does not work anymore with the latest update

[ahmedabdelkawy]

All restart functionality is broken for old jobs (not sure how to allow others to reproduce this)

error: rror saving warn (key /Ni111_Mo_surface_sub1_cov/input/vasp_dict/eddrmm_handling): h5io_browser doesn't support saving elements of type "<class 'str'>" to HDF!

• switching pyiron versions to the old ones did not work
• manually changing h5io_browser did not work
• old problematic jobs: type(job_test['input/vasp_dict']) -> dict
• new working jobs: type(job_test['input/vasp_dict']) -> pyiron_base.storage.hdfio.ProjectHDFio
