Fix common build dir implementation in instance executor
What does this MR do?
Fixes implementation of use_common_build_dir
in the instance executor.
Why was this MR needed?
Current implementation will most probably cause a panic and runner process crash for every started job, when use_common_build_dir = true
would be set.
What's the best way to test this MR?
What are the relevant issue numbers?
