Clean up example code
* Consistently use `const` to introduce variable bindings.
* Don't rely on `xText` from the first example in the second one.
* No (more) need to query for base interfaces.
* No (more) need to delete interface references.
* Add a missing delete of Any `next`.
* Remove a redundant empty line.
* Adapt to our 100 character line width.

Some usage examples through javascript of the current implementation:
```js
// inserts a string at the start of the Writer document.
-let uno = init_unoembind_uno(Module);
-let css = uno.com.sun.star;
-xModel = Module.getCurrentModelFromViewSh();
-xTextDocument = css.text.XTextDocument.query(xModel);
-xText = xTextDocument.getText();
-xSimpleText = css.text.XSimpleText.query(xText);
-xTextCursor = xSimpleText.createTextCursor();
-xTextRange = css.text.XTextRange.query(xTextCursor);
-xTextRange.setString("string here!");
-xModel.delete(); xTextDocument.delete(); xText.delete(); xSimpleText.delete();
xTextCursor.delete(); xTextRange.delete();
