It was called twice once with and without X as our implementation of
setRootInfo() missed some calls.

This was done to avoid a bug as setRootInfo() didn't update everything.
This patch aims to resolve that at the root cause.

I tested the original conditions of the patch with an empty kwinrc and a
file in /etc/xdg/kwinrc setting desktops to 2 and everything loaded
correctly.
