search: Handle ()() in autofix

Created by: keegancsmith

Noticed this flakey test failure in CI. It is a legitimate issue were we do not properly escape ()(). It escaped it as \(\)(). This is due to the replacement regex checking for the preceding character being \, which means when ReplaceAll runs after replacing the first () the regex won't match since ^ means beginning of string, not match.

I wasn't sure how to make this happen in a regex, so wrote a function implementing the functionality.
