Welcome: Fix initial welcome screen layout for small window

The visibility of some Welcome screen elements depends on the size of
the Welcome screen.

When starting Qt Creator with a small initial window size, the hiding
of the side bar did not work.

This change removes the check for visibility as the main fix for
QTCREATORBUG-29800. The QTimer::singleShot is replaced with immediate
layout calculation in order to avoid another initial layout issue which
is only visible during startup.
