Update to job definition does not fill in the input file correctly if not in base folder

[mimikwang]

Description

When I edit a job definition created from a file in a subfolder, the input file does not include the path. I have to explicitly update the path as it defaults to the home path. This means that it fails - unless I have happen to have a file of the same name in the base folder, then the job definition is updated incorrectly with the wrong file.

How to reproduce

1. Create a subfolder
2. Create a notebook
3. Create a job definition
4. Edit the job definition and save

Expected behavior

When editing the job definition, the full path should be populated instead of just the file name
