Set the LocalName for the spec using a separate argument in the NewSpec() constructor instead of reusing the `source` arg. The name is already available in the calling scope in the client's Resolve() method. If the LocalName is an empty string, default to the remote (source) reference. This is a change from the previous behaviour which only used the base source.Name(). The full source corresponds to the user-provided source value, which includes any specified tag or digest. The `name` argument which is used in the `Resolve()` function should always correspond to the user-provided container name.
