Documents are not returned with SQL interface

[kkorsakov]

Step to reproduce:

1. Create space and insert documents as in sample tarantool> box.schema.create_space('TEST_DOC', {if_not_exists = true}) tarantool> doc.create_index(box.space.TEST_DOC, 'primary',{parts={'id', 'unsigned'}, if_not_exists=true}) tarantool> doc.insert(box.space.TEST_DOC, {id=1, foo="foo", bar={baz=3}})

2. Verify that data is inserted tarantool> for _, r in doc.select(box.space.TEST_DOC) do print('tuple:', json.encode(r)) end

tuple:  {"bar":{"baz":3},"foo":"foo","id":1}
---
...

3. Select data with SQL interface tarantool> box.sql.execute([[select * from TEST_DOC]]);

Expected: tuples with documents.

Actual: SQL error

- error: 'no such table: TEST_DOC'
...

Additional data: tarantool> box.sql.execute([[SELECT * FROM _space;]])
