Fix more even more crashes with newer QT versions

This time I actually went through the docs and found all the elements in
`qproxystyle` that didn't have a default value for the widget, which are

```
sizeFromContents
subControlRect
subElementRect
```

and then went through the entire Manuskript project with grep and made
sure I didn't leave any more places that needed this change.

I confirmed that I would also crash in the full screen editor -- I'm not
sure how to get to the collapsibleGroupBox code within Manuskript
itself, but from looking at the code, it's almost definitely the same
issue.
