Quick Assist "Replace method call with property expression" does not work on setter with named argument(s)

Consider the following:
```groovy
void setX(Map map) {
}
setX(p1:null, 'p2' : new Object() )
```

Executing "Replace method call with property expression" (Ctrl+Shift+,) on "setX" does not replace `setX(p1:null, 'p2' : new Object() )` with `x = [p1:null, 'p2' : new Object() ]`.
