fix #195891 reduce save online window height

[jeetee]

only verified in the designer view of QtCreator, but should be fine given the minimal change

You can test it using the -e option

[WIP] while the initial size of the window is fine, it snaps to a bigger minimal size once you attempt to resize it.

From the console:
Warning: setGeometry: Unable to set geometry 615x550+493+155 on QWidgetWindow/'U
ploadScoreDialogWindow'. Resulting geometry: 615x729+493+155 (frame: 8, 30, 8,
8, custom margin: 0, 0, 0, 0, minimum size: 420x473, maximum size: 16777215x1677
7215). (:0, )

Especially interesting is the minimum size it gives itself for the frame, whilst not allowing you to go that small.. I'm wondering if it has to do with the contents being a FormLayout here rather than a GridLayout..
I'll dive a bit deeper into what other sizehints are set inside of the Form to see what is causing this high a minimal height.

Looking into it, did you find anything else?

Not too much; slightly annoyed and baffled by it.
Most occurrences of that error I can find are mostly related to either not setting the geometry on a window object, but a widget; or setting a geometry that is smaller than the window managers minimal size (for example to ensure visibility of title bar/buttons). Neither should be the case here.

This QTBUG seems slightly related (at least the same error response, but triggered by changing OS scaling of text) from January: https://bugreports.qt.io/browse/QTBUG-58027

And then there is this forumpost from May which seems to be the exact same issue, but has zero responses so far: http://www.qtcentre.org/threads/68266-window-size-out-of-control-error-is-setGeometryDp-Unable-to-set-geometry

Here is my take on it #3260
