[Helm plugin] Remove unnecessary context check

[castelblanque]

Signed-off-by: Rafa Castelblanque rcastelblanq@vmware.com

Description of the change

Trivial PR removing unneeded checks for provided context cluster.
Cluster is not strictly required, as it will fall back to the Kubeapps cluster if not specified. See code in charge here.

Otherwise, an error like this was returned:

ERROR:
  Code: InvalidArgument
  Message: Invalid GetPackageRepositorySummaries response from the plugin helm.packages: rpc error: code = InvalidArgument desc = no valid context provided

Benefits

Specify cluster context for operations in Helm plugin is not required.
