If the user set to be configured by cloudbase-init is already added, but no logon session has been created for that user, the profile registry key does not exist. As a consequence, the SetUserSSHPublicKeysPlugin fails, as it cannot retrieve the home directory from the registry key. Change-Id: I4226a1c08e940717709e65ba932ce15c8ce37aed Closes-Bug: #1415198
