Issue:
[Helm 3] helm package requires argument
<!-- If you need help or think you have found a bug, please help us with your issue by entering the following information (otherwise you can delete this text): -->

According to the description for `helm package`:

> If no path is given, this will look in the present working directory for a
Chart.yaml file, and (if found) build the current directory into a chart.

But this is not the case, shown by running `helm package`:
```
Error: need at least one argument, the path to the chart
```

Recommended solution, rather than throwing an error if no args are provided, append to `args`:
```
if len(args) == 0 {
  args = append(args, ".")
}
```

Should be an easy enough PR. 😉 Only one change to the tests should be needed. I don't have `golangci-lint`, so I couldn't run the tests locally.

Output of `helm version`:
```
version.BuildInfo{Version:"v3.0.0", GitCommit:"e29ce2a54e96cd02ccfce88bee4f58bb6e2a28b6", GitTreeState:"clean", GoVersion:"go1.13.4"}
```

Output of `kubectl version`: N/A

Cloud Provider/Platform (AKS, GKE, Minikube etc.): N/A
