Kiril Vladimirov c30fc51b03 fix(datasource/CloudSigma): Make sure public ssh key is not empty
Even when public ssh key is not set by the user, CloudSigma's server
context has a key `meta.ssh_public_key` which is just an empty string.
So instead of just relying on the "comma ok" idiom I make sure the value
is not an empty string.
