QML/JS -> Reformat File with comment at the start adds 2 NL

Running QML/JS -> Reformat File on a qml file from the examples (that has the usual copyright comment at the start) will add two additional newlines to the beginning of the file.

Test case:

Before:

/* Hello World */

import QtQuick

Item {
}

After:

/* HellO World */
import QtQuick

Item {}
