Fix compilation of examples with QStringBuilder

In sub-attack an interview, one can't make two implicit conversions at
once, so explicitly convert to the right type.

The change in the torrent example is required because of
https://codereview.qt-project.org/16168 (commit 9491272)
But in that case, using a QByteArray is better anyway.
