fix(sdk): fix console logging resumption, avoid overwrite

[kptkin]

Description

• Fixes WB-8698, WB-12526

This PR fixes a resume case where we would ignore the offset of the already streamed console lines. With the fix we always start from the provided offset.

Testing

This was tested manually and the goal is not to break the existing functionality of a single run. Based on the code it should be fine as by default the offset is 0.
