fix(pipeline): add incomplete as a finished state for pipeline steps. Fixes #384

[matei-radu-adrian]

Description

A new status (incomplete - which is a final state) for pipeline steps was added in 2023.6.0 release of CM and this prevents in some cases the current step method to actually detect which is the proper current step (the one that is running, waiting, etc.)
