Anton Kudryavtsev 9c8a8e90a6 QString: fix append(const QStringRef &str)
Use QStringRef::isNull instead of QStringRef::string()
for validation. Non-NULL str.string() may yet leave us
with a useless str.unicode(), which is the actual problem here;
whereas !str.isNull() does really confirm that str.unicode()
is sensible.

Such test prevents situation like:

const QString a;
QString b;
b.append(a); // b.isNull() == true
b.append(QStringRef(&a)); // b.isNull() == false

Auto test updated: create QStringRef from QString directly, without
any condition.
