fix migration from 0.82 data store

Subject: [PATCH] fix migration from 0.82 data store (#1838)

Upgrading directly from 0.82 to 0.86/0.88 didn't migrate the data store
contents because LayoutManager._is_empty() doesn't check for 0.82 data store
entries.
This patch fixes _is_empty() to recognize 0.82 data store contents.
