BUG/TYPO CI Version 3.1.8

I just updated to CodeIgniter 3.1.8 and directly stumbled on a `typo` within the DB_query_builder.

If you use the following like, you will encounter a error:

PHP Code:

$this->db->like('field', 'value', 'BEFORE'); 


This will result in a Database Error like:
syntax error '%'value' ESCAPE '!' ...

The % is placed before the quotes.


Fix:
Edit the DB_query_builder.php file on line 973 from:

PHP Code:

case 'before':                    
$v = "%'{$v}'";                
break; 


to:

PHP Code:

case 'before':                    
$v = "'%{$v}'";                
break; 


Didn't saw a thread of this yet, in case i missed i'm sorry
