Oddity with chart searching

[sstarcher]

• Running helm search private/elasticsearch returns results
• Running helm diff upgrade derp private/elasticsearch --allow-unreleased fails with

Error: chart "elasticsearch" matching  not found in private index. (try 'helm repo update'). No chart version found for elasticsearch-
Usage:
  diff upgrade [flags] [RELEASE] [CHART]

Examples:
  helm diff upgrade my-release stable/postgresql --values values.yaml

Flags:
      --allow-unreleased       enables diffing of releases that are not yet deployed via Helm
  -h, --help                   help for upgrade
      --reset-values           reset the values to the ones built into the chart and merge in any new values
      --reuse-values           reuse the last release's values and merge in any new values
      --set stringArray        set values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
      --suppress stringArray   allows suppression of the values listed in the diff output
  -q, --suppress-secrets       suppress secrets in the output
  -f, --values valueFiles      specify values in a YAML file (can specify multiple) (default [])
      --version string         specify the exact chart version to use. If this is not specified, the latest version is used

Global Flags:

It looks like the root cause of the issue is only having pre-released versions and no released version. When helm-diff is searching it's searching only for released versions. The default behavior of helm search is to show pre-released versions.

@sstarcher What if you added --version ">0.0.0-a" to helm diff upgrade?

The context is helm/helm#2407 and technosophos/k8s-helm@28ec923.

helm-diff seems to run an equivalent of helm fetch, so the fix should be brought by how we could make helm fetch to discover prereleased versions.
