Risk of data loss

[domagoj-42]

If I restart an experiment with the same name, the old recordings from the same rec directory get wiped. I am not sure if this is intended behaviour, but even if it is, it runs the risk of accidental user data loss.

Interesting - it's not intended

Typical sequence should be

• start_recording triggered
• module starts recording, adds each new file it creates to "session_files" list
• when stop_recording triggered, stop recording to files and check if auto export enabled
• if auto export enabled, export to controller
• if delete on export enabled, auto delete after successful export

The use of a session_files list is relatively recent and was previously handled by matching experiment_name string against files in rec/. I imagine there's some code in modules/export.py or modules/module.py still auto-deleting files based on experiment name string instead of them being in session_files
