Fix quadratic behavior when converting from QVariant
The old code called insert for each item, leading to constant
reallocation of the data structure. Instead rely on the fact
that a QVariantMap (as well as the variant list) is sorted, so
we can convert to the QJson data structure in one go without
lots of reallocations.
