executor: insert negative primary key into auto_random table won't trigger rebase

[tangenta]

What problem does this PR solve?

For now, inserting a negative number into auto_random table will trigger rebase:

create table t (a int primary key auto_random);
insert into t values (-99999999);
insert into t values ();
 select * from t;
+------------+
| a          |
+------------+
| -99999999  |
| 1510612738 |
+------------+

The hex representation of 1510612738 is 5A0A1F02. A lot of auto ids are consumed.

It is more intuitive not to rebase in this case.

What is changed and how it works?

Only rebase auto_random id when the inserted number is positive.
