    qt: fix use-after-free pattern
    
    qstring.toUtf8() returns a QByteArray object and .constData() returns
    a pointer inside that object. It is not safe to store this pointer as
    it will become invalid after the statement. Store a const reference
    instead. (Due to scoping differences, some are copy-assigned though.)
    
    In the UAT dialog, strlen(bytes.constData()) has also been replaced by
    bytes.size() as an optimization.
    
    Caught by ASAN.
