sw comments on frames: fix DOC handling

The export part didn't use HasFlysAt() to decide what to do with empty
annotation marks.

Regarding the import side, the only problem was that the start of the
annotation range wasn't adjusted to cover the comment anchor, similar to
what the UI and the UNO API already does.
