Marc Mutz 33f7eb44ff dbus test headers: port away from Q_FOREACH
Headers must be free of Q_FOREACH uses if we want to white-list only
those .cpp files that still use Q_FOREACH in order to enable
QT_NO_FOREACH by default.

In common.h, the situation is pretty clear: the loop bodies clearly
don't modify the container being iterated over.

In MyServer, the situation is not clear at all, and this author
doesn't have the time to investigate, so take a copy and iterate over
that (eactly what Q_FOREACH does), and leave a comment.

As a drive-by, fix missing {} around multi-line loop bodies.
