ExcludedCharts does not work with multi-level ChartDirs

[stawii]

Is this a BUG REPORT or FEATURE REQUEST? (choose one): BUG REPORT

Version of Helm and Kubernetes:

N/A

What happened:

ExcludedCharts does not work when ChartDirs contains path with more than one level: ie. charts/apps or charts/my/path/is/longer/than/yours.

What you expected to happen:

Chart is excluded correctly.

How to reproduce it (as minimally and precisely as possible):

chart-dirs:
  - charts/apps

excluded-charts: # neither of those works
  - charts/apps/chart-name
  - chart-name

Anything else we need to know:

I guess it is this line

chart-testing/pkg/chart/chart.go

Line 721 in 2407e7d

if len(pathElements) < 2 || util.StringSliceContains(cfg.ExcludedCharts, pathElements[1]) {

- the pathElements is [charts, apps, chart-name], so chart name is 2 not 1 in this example. This will be different if path has more levels.
