insert() doesn't return boolean but CodeIgniter\Database\MySQLi\Result

[bvrignaud]

The insert function (in BaseBuilder.php) doesn't return boolean value as documention and php code doc said, but :

• on success : return CodeIgniter\Database\MySQLi\Result
• on error : exception

I think, it's more a documention error ?

What do you think ?
I can send you a PR if you want.
