This PR fixes an issue where the cgroup inode when the container id is "".
During testing of the last commit of this PR, we found out that the inode was sent and container tags was finally retrieved.
But actually, it was only because we had another bug in container id resolution that was fixed here. We were overriding a faulty container-id. We shouldn't override the container-id (actually it's not problematic). But we should at least retrieve the container-id when it's not found.

The new test cases should cover everything
