Fix behavior change QStringList::join() for null
Before 4.6.2 both str.isNull() and str.isEmpty() return true for the
following code.
QStringList list;
QString str = list.join(QString());
This commit revert the behavior change introduced by
7461ed5227e3002c4a6f74d458aa0255b7c1217d. Joining null
QString was giving a empty string instead of a null
string.
