"Tools -> QML/JS -> Reformat File" does not honor "Qt Quick -> Code Style" tab size

Even though the tab size and indent size in "Qt Quick -> Code Style" are not 4. "Tools -> QML/JS -> Reformat File" still uses 4 spaces to reformat file.

To reproduce:

1. Open Tools -> Options
2. Click "Qt Quick" on the left.
3. Click "Copy..." button on the right. Click OK.
4. Click "Edit..." button on the right.
5. Change "Tab size" and "Indent size" to 2.
6. Click OK and OK to go back to editor.
7. Open a QML file.
8. Click "Tools -> QML/JS -> Reformat File". File is reformatted to tab size of 4 spaces.
