make the previous change foolproof

in order to preserve the old behavior in a (corner) case where string was created
from the raw data with a shorter lifecycle, just call QString's realloc()
that will copy the data and thus guarantee it's consistence later.
example:
QCFString str;
{
    QString qstr("I'm stupid");
    str = QCFString(QString::fromRawData(qstr.data(), qstr.size());
}
