Bug: multi-column WHERE not prefixed

[MGatner]

Describe the bug
When referencing a fully-qualified column as the target of a WHERE operator the second table name is not prefixed.

CodeIgniter 4 version
Latest develop

Affected module(s)
Builder (tested with MySQLi)

Expected behavior, and steps to reproduce if appropriate

$config['DBPrefix'] = 'foo_';
...
$builder = db_connect()->table('mytable');
$builder->where('mytable.created_at < mytable.updated_at')->get()->getResult();

The above will thrown an exception "Table not found: mytable" because the generated query looks like:
SELECT * FROM foo_mytable WHERE foo_mytable.created_at < mytable.updated_at

(Notice the missing prefix on the latter table reference)

Context

• OS: Ubuntu 18.04
• Web server: Apache
• PHP version: 7.3
