[bfss] Make ``current_fs_path`` return None when an attribute has no value
current_fs_path was returning the future fspath when no value was defined.

* This tricks the storage into believing that updating the attribute content is
not necessary. The file was written but the attributes was not updated. as a
result the assignement was not made.
