Fix GuiChat ASM surrounding too many instructions with if statement

[Alexdoru]

The code injected in the GuiChat.drawScreen method is surrounding all the code from the start of the method up to the drawRect call with an if statement. https://github.com/Sk1erLLC/Patcher/blob/4ce6e196e5ad1339f8a0ab96eb5680c2f6464583/src/main/java/club/sk1er/patcher/asm/render/screen/GuiChatTransformer.java#L67

If another ASM mod injected code at HEAD, that code will be wraped too with the if statement.

I suggest deleting that ASM and instead use a mixin using the @WrapWithCondition targeting the drawRect call
