Source mode not working for new datasets

[KonstantinHebenstreit]

Loading datasets med_qa_open and the MMLU datasets does not work in source view.
(It is working in thoughtsource view, so generating CoTs etc is working.)

[KonstantinHebenstreit]

deactivated the global test for checking if the source view is working for all files for now (test_load_collections/test_source)
