Api does not have the job_chain path in job_chain.name

Thus, it remains compatible with existing applications, I propose to implement a new property with the path to the job chain.

Now:
----------
job_chain.name = string
job_chain.name returns name of the job chain

New:
------
job_chain.path = string
job_chain.path returns the path of the object relative to the live folder (including object_name) starting with a "/"

Example:
"/test/x"
