### Godot version

v4.0.stable.official [92bee43ad]

### System information

Windows 10

### Issue description

In my project i have a function name called "get_or_connect" which also had 3 arguments, where the Conversion then put the last 2 args inside of a callable, bricking the method.

Here it seems that it has a regex like "connect(" and if that would be expanded to ".connect(" this kinds of false replacements could be prevented.

### Steps to reproduce

Open the MRP and open it with godot 4 and convert it to godot 4.

Now there should be a lot of renames in the one Script "Main.gd" which are incorrect. You can check the script before the conversion to check or see in the comments
