Avoid --skip-refresh on local charts (#541)

All the dependencies get correctly installed when dealing with remote charts. If there's a local chart that depends on remote dependencies then those don't get automatically installed. See #526. They end up with this error: ``` Error: no cached repository for helm-manager-b6cf96b91af4f01317d185adfbe32610179e5246214be9646a52cb0b86032272 found. (try 'helm repo update'): open /root/.cache/helm/repository/helm-manager-b6cf96b91af4f01317d185adfbe32610179e5246214be9646a52cb0b86032272-index.yaml: no such file or directory ``` One workaround for that would be to add the repositories from the local charts. Something like this: ``` cd local-chart/ && helm dependency list $dir 2> /dev/null | tail +2 | head -n -1 | awk '{ print "helm repo add " $1 " " $3 }' | while read cmd; do $cmd; done ``` This however is not trivial to parse and implement. An easier fix which I did here is just to not allow doing `--skip-refresh` for local repositories.
