Minor changes

[arnavjk007]

This is good but let's update this to return a list of labs when we pass in user id. Because what if a user is a part of multiple labs?

[arnavjk007]

lets also add .lean() and .sort({ createdAt: -1 }) to ensure labs returned will always be in same order

Let's try to do this format where we get the item and then check if it exists. If it doesn't then we return item not found otherwise we return it like this:

const item = await LabModel.findById(id).exec();
if (!item) {
throw new NotFoundError("Item not found");
}

await item.deleteOne();
