Refactor rename symbol of variable will impact named parameter

[momala454]

Describe the bug Refactoring a variable will also rename the named parameter

To Reproduce

function helloWorld(int $myParameter): bool {
    return true;
}

$myParameter = 'hello';

$result = helloWorld(
    myParameter: 6
);

Renaming the variable $myParameter to $myParameter2 will also change the call to the helloWorld function like this

$result = helloWorld(
    myParameter2: 6
);

Take note that the named parameter itself in the function declaration is not changed

Expected behavior Only the variable should be renamed
