Quick: handle missing default system; enable work as default system locally

[rstijerina]

Overview

• Fixes case where the default system is not the first system in the list
• Fixes case where no default is set, and sets first system as default if so
• Adds the scratch filesystem, and removes the my data corral filesystem
• Sets the work filesystem as default locally

Testing

1. Spin up the portal and confirm the work filesystem is default
2. Confirm the scratch filesystem also works
3. Remove the default flag from the work filesystem in _PORTAL_DATAFILES_STORAGE_SYSTEMS and confirm work is still set as default
4. 3. Remove the default flag from the work filesystem in _PORTAL_DATAFILES_STORAGE_SYSTEMS and make another filesystem default, and confirm that system now shows as default
