KCModuleQml: Also force height in addition to width
KCModuleQml's ApplicationItem sets its width to that of its
containing Window. This allows e.g. a ScrollViewKCM to fill the
entire view with a ListView which uses anchors.fill: parent.
In common circumstances, this works without also setting height. Notably, System Settings does not need it. However, a lack of height setter breaks down in these conditions:
- When opening the KCM inside kcmshell6 instead of System Settings,
- and also, the ScrollViewKCM (or such) is opened in a sub-page.
In this case, the ApplicationItem will remain at its default
implicitHeight and anchors.fill: parent won't do its job.
To fix this, force height in the same way as width is.

Anything else that already works, like the same page in System Settings, keeps working because apparently it overrides the height through some other means.
