Fixed HelmRelease delete

[slysunkin]

Description

Fixing #217

This fix is intended to resolve an issue when deletion of HelmRelease resulted to non-deleted (orphaned) objects.

Initially available objects for helm release:

k get AWScluster -n hmc-system                                                     
k get AWSMachineTemplate -n hmc-system
k get Cluster -n hmc-system
k get K0sControlPlane -n hmc-system
k get K0sWorkerConfigTemplate -n hmc-system
k get MachineDeployment -n hmc-system

Several minutes after make dev-aws-destroy:

k get AWScluster -n hmc-system
k get AWSMachineTemplate -n hmc-system
k get Cluster -n hmc-system
k get K0sControlPlane -n hmc-system
k get K0sWorkerConfigTemplate -n hmc-system
k get MachineDeployment -n hmc-system

P.S. Minor misprint was fixed as well.

If you make it suspended, flux won't remove the helm release and underlying resources
