fast-export: Omit tags that tag trees
Commit c0582c53bcf4e83bba70e1ad23abbad31f96ebc8 introduced logic to just
omit tags that point to tree objects. However, these objects were still
being output and were pointing at "mark :0", which caused fast-import to
crash. This patch makes sure such tags (including deeper nestings such
as tags of tags of trees), are omitted.
