Once uploaded source directories can no longer be modified

[hartmutschmidt]

Modifications made to files that are located in a directory that is provided as the source argument of the submit_job method are not transmitted to the site local agent. Only the originally submitted files are available although modifications were made or new files were added to the directory.
The files are uploaded and updated correctly to a source_code folder in the EBRAINS-Drive, but the URL provided in the code field of the corresponding job on the site local agent directs to a zip file that still contains the originally uploaded files.
Even after several re-submits the files are not updated.
