Code completion inserts incorrectly in QML file

1. Open a QML file.
2. In the file, type a misspelled item name, e.g. "Rextangle".
   This will be underlined because it is a syntax error.
3. Move the cursor back to the wrong character and fix it, e.g. change the "x" to "c".
   Creator will show a code completion popup offering the correct item name, e.g. "Rectangle".
4. Press Enter.
   Creator will insert the item name regardless of what's already written, e.g. you will get something like "Rectangletangle".

After inserting, the item name should be correct. In C++ files, this works correctly.
