toString

[joris-planorama]

With

QList<Variant> numbers = {4, 8, 15, 16, 23, 42};
auto s = QDjangoWhere("number", QDjangoWhere::IsIn, numbers).toString();

s is QDjangoWhere(key="number", operation="IsIn", value="", negate=false)
without the numbers (value is empty).

Note: My real problem is to make something similar to QDjangoWhere::sql or a serialize of a QDjangoWhere and I tried to use the toString() for that.
