--recreate-pods set twice in tests for chart installation about reckoner

This is because for some reason the helm_args in the course.yml is getting applied twice now:

2019-01-07 16:25:20 root[26566]    DEBUG helm upgrade --recreate-pods --install metrics-server stable/metrics-server --namespace=infra --recreate-pods --version=2.0.3 --set=args[0]=--kubelet-insecure-tls --set=args[1]=--kubelet-preferred-address-types=InternalIP --set=args[2]=--metric-resolution=30s --set=args[3]=--v=3

I believe it is because an instance of the helm client is created and helm args are set:
https://github.com/reactiveops/reckoner/blob/master/reckoner/course.py#L58
then helm args are later appended again to the arguments per chart:
https://github.com/reactiveops/reckoner/blob/master/reckoner/chart.py#L212
