Code Editor 2: [Rename Identifier] Refactoring function names does not work if there is whitespace after the brackets on the declaration line

[gnysek]

Description

When creating scripts, there's a function with same name created inside it.
When renaming script, if it contains function with same name, it's renamed but only if there's no space between round and curly brackets.

So this would get renamed:
function Script1(){
but this won't:
function Script1() {
(space is after ())

Steps To Reproduce

1. Create script
2. Add space between () and {
3. Rename script

You can also try to rename (F2-key) scripts inside example project to see it.

The issue is much worse than this, because GameMaker renames all function calls even when failing to rename the function definition, breaking code. These are two separate issues. I reported the other one here: #8346
