Annotator meta property not stored

[jankolkmeier]

The "Annotator" meta property is not being stored in the meta field of annotation lists.
I.e., opening a project with a tier like this:

<?xml version="1.0" ?>
<annotation ssi-v="3">
    <info ftype="ASCII" size="3" />
    <meta annotator="JAN" role="b"/>
    <scheme name="..." type="DISCRETE"  color="#FFEBEBEB">
        <... />
    </scheme>
</annotation>

Will correctly show the annotator in the interface. However, storing the same project to disk again however will result in empty annotator field in the <meta /> tag.

I've fixed this for me by writing Meta.Annotator instead of Meta.AnnotatorFullName in AnnoListFile (see 8455727), but I'm not sure if that will break things elsewhere.
