Here is how to reproduce the bug:

1. Start path-noexist-bug.leo with --no-cache.

2. Change the text of the root node.

3. Save the outline twice.

The first time, a trace in fc.putVnode will report forceWrite = True
and isOrphan = True.

The second time, the trace will report both are False. This is the
proximate cause of the data loss.

So it looks like the *first* save clears the orphan bit improperly,
creating a time bomb.
