*8859* Improve article copyright/license affixing

PR for testing and comment; Do not merge.
This is the intent, and the effect in my testing.  I'm still waiting to hear back on the testing by my publishers.

The method initializePermissions() should only affect unset fields.  Modified fields will not be re-initialized.  The effect is that only the (missing) copyright year will be initialized in the publication process, unless the copyright holder or license URL we unable to be set automatically earlier.

Are you seeing otherwise?
