fix whacky behavior of QScriptValue::toString() for QVariant

For some types, an empty string is the correct and complete
conversion of the type. If the result is an empty string, use
QVariant::canConvert() to determine if that is indeed correct,
before falling back to the "string-conversion-not-available"
path.
