Fix editor log search ignoring BBCode formatting in messages

When searching in the editor output log, messages with BBCode formatting
(like [color=red]text[/color]) would not be found when searching for the
plain text content. For example, searching for "Example is" in a message
"[color=blue]EXAMPLE[/color] is super cool" would fail to find the match.
