Upgrade old element type names in saved query presets too

A query saved to nomenclature.json (Load/Save in the query editor, since
2020) before June 2022 still says element_type = 'Simple'. Loading it
ticked none of the type boxes and kept the old query, so the new table
came out empty. Pass it through LegacyElementTypes::upgradeQuery() as
ProjectDBModel::fromXml() now does.
