Reverted changes introduced in #6010

This commit reverts changes introduced in #6010 due to a massive
regression reported in #6708. An attempt to fix the problem in
https://github.com/helm/helm/pull/6709 seems to be unreasonably clumzy
and hacky, therefore reverting the offensive change seems to be the most
pragmatic solution.

This reverts commits:
  * 70cd32c4ce.
  * 9014bd9c50.
