Issue with demultiplexing for specific run folder with -r flag

[wintun12]

There is an issue with running manual demultiplexing for specific run folder with -r flag.
I think the issue lies in line 85 of demultiplex.py, where runfolder_names = [self.runfolder_names] should be runfolder_names = [runfolder_names]. self.runfolder_names has not been defined yet when the code in line 85 is trying to call it.

This issue only occurs when the run folder name is provided (e.g. -r <run_folder_name>). If the run folder name is not provided, this line is skipped so no issue. Cron job command line in the workstation does not have -r flag since it does not run for specific run folder, so it's not issue with current cron job command.
