Answer 1

You have to add parent dependencies in your public function __construct()

public function __construct(
    \Magento\Framework\Model\Context $context,
    \Magento\Framework\Registry $registry,
    \Magento\Authorization\Model\ResourceModel\Role $resource,
    \Magento\Authorization\Model\ResourceModel\Role\Collection $resourceCollection,
    \Sugarcode\Test\Model\Total\FeeFactory $feeFactory,
    array $data = []
) {
    parent::__construct($context, $registry, $resource, $resourceCollection, $data);
    $this->_feeFactory = $feeFactory;
}

Then remove your generated folder, clean cache and check again.

Answer 2

You just need to replace your constructor and need to clear generation. Below I have added constructor code please update it in your file and check after that.

public function __construct(
        \Magento\Framework\Model\Context $context,
        \Magento\Framework\Registry $registry,
        \Magento\Framework\Model\ResourceModel\AbstractResource $resource = null,
        \Magento\Framework\Data\Collection\AbstractDb $resourceCollection = null,
        array $data = array()
    ) {
        parent::__construct($context, $registry, $resource, $resourceCollection, $data);
    }

Still you have any query let me know.
