Depends on D26993
I suspect this will fix a few bugs whilst we're at it.
There were a lot running after startplasma has started, so wouldn't have been synced properly to the DBus env.
I don't understand why this changes
I don't either but it wouldn't build without.
We haven't called start on any of the jobs, so they do nothing
Also given they're kjobs do we want:
auto job = new UpdateEnvJob()
so we don't delete the job immediately?
