style(php-shim): drop the underscore from used parameter names

These parameters kept the leading underscore they were given while their
function bodies were still todo!(), and the underscore now reads as "this
argument is ignored" for arguments the bodies do use.

Removing the prefix stops it from suppressing four clippy lints, fixed
alongside: one redundant field name, and three `&mut Vec` parameters that
only need a slice.
