On Wayland there is a special case when decorations are enabled,
where we post an initial update request to ensure widgets are
redrawn after the buffer is recreated (see
af7b60ade5c4be81cbc58eb18307c017d5594071 in qtwayland). To
make sure the test behaves the same on Wayland as on other
platforms, we disable client-side decorations when running
these tests.
The flag is primarily required for the requestUpdate() test
at the moment, but it is only queried once per application
run, so it has to be set before any tests are run.
