ExtensionLoader: Use a QMultiHash

Fix deprecation warnings:
extensionloader.cpp:65:84: warning: ‘QList<ValueType> QHash<K, V>::values(const Key&) const [with Key = QString; T = QJsonObject]’ is deprecated: Use QMultiHash for hashes storing multiple values with the same key. [-Wdeprecated-declarations]
extensionloader.cpp:108:44: warning: ‘QHash<K, V>::iterator QHash<K, V>::insertMulti(const Key&, const T&) [with Key = QString; T = QJsonObject]’ is deprecated: Use QMultiHash for hashes storing multiple values with the same key. [-Wdeprecated-declarations]
plugin.cpp:82:63: warning: 'QList<T> QHash<K, V>::uniqueKeys() const [with Key = QString; T = QJsonObject]' is deprecated: Use QMultiHash for hashes storing multiple values with the same key. [-Wdeprecated-declarations]
