Subject: [PATCH] Add empty text if children are empty (#3889)

If line 170 is not added issues like https://github.com/ianstormtaylor/slate/issues/3625 start surfacing.
Because the deserialize example is mostly directly copy-pasted into projects, the added line would save many head-scratching down the lane.
