No lineage returned for renku run ... <output folder>

[ciyer]

Description

If a script is implemented to take an output folder as an argument and write files into the output folder, the command line correctly records lineage, but the linage returned by the graph is not correct.

Example:

This file has no lineage in the graph:

https://dev.renku.ch/projects/cramakri/folder-output-test/files/lineage/data/output/count.csv

The response from the graph is:

{"data":{"lineage":null}}

But renku log returns this:

$ renku log
*  8d7ddaac data/output/count.csv
|           (part of data/output directory)
*    8d7ddaac data/output

@ |  8d7ddaac data
