Updat extra/empty.snap with a nice empty snapshot in the new format.
A fix and a test case for gh-253, gh-289.

Add a owner for a user, use owner privileges to check
whether or not it's possible to drop a user.

Rebuild empty.snap, it can be used as bootstrap.snap to
fill the schema from scratch.

Update bootstrap.snap with an index on _user[2] (second
field in _user).
