Most task and workflows display "Listing source artifacts not yet implemented for this task type"

Most tasks and workflows currently display "Listing source artifacts not yet implemented for this task type" instead of the actual source artifacts. The source artifacts can be recovered by looking at the task data, but they should likely be linked properly.

This should be done for all tasks and workflows, and should be mandatory for new tasks and workflows in the future. It should also show the promise details when the artifact is not yet available.
