Convert some QVERIFY2() with useless messages to QVERIFY()

Telling us the condition tested should have been true is what
QVERIFY() does anyway, so don't go to the whole trouble of saying the
same thing - and wrapping it in in a QString() merely in order to then
qPrintable() it back out again, pointlessly converting a C-string to
unicode and back again.

At the same time, skip one other qPrintable(QString("...")) without
.arg() formatting; and change the check it's the message for to use
QL1S::arg() instead of QString::arg().
