[BUG] v5.0.4 ILiteCollection.Find() does not work with enum

[hopson-2]

Version
5.0.4/Windows 10/net framework 4.7,2

Describe the bug
the ILiteCollection.Find() method does not appear to work with enum

Code to Reproduce
LINQPad v5.41/C# Program

void Main()
{
	const string databaseFilename = @"C:\temp\litedb_504_test.db";
	using (LiteDB.ILiteDatabase liteDB= new LiteDatabase(databaseFilename))
	{
		ILiteCollection<Customer> collectionCustomer = liteDB.GetCollection<Customer>("Customer");
		liteDB.DropCollection("Customer"); //remove previous test customers from DB
		
		Customer doeJohn = new Customer()
		{
			Name="John Doe"
			, Description = "Test Customer"
			, PaymentMethod = PaymentMethodType.Cash
		};
		Customer doeJane = new Customer()
		{
			Name = "Jane Doe"
			, Description = "Test Customer 2"
			, PaymentMethod = PaymentMethodType.CreditCard
		};

		collectionCustomer.Upsert(doeJohn);
		collectionCustomer.Upsert(doeJane);
		collectionCustomer.EnsureIndex(x => x.Id);
		
		collectionCustomer.Find(x => x.Name=="John Doe").Dump("Find John");
		collectionCustomer.Find(x => x.Name.Contains("Doe")).Dump("Find all Doe");
		collectionCustomer.Find(x => x.PaymentMethod==PaymentMethodType.Cash).Dump("Find all cash with enum does not work");
	}
}

// Define other methods and classes here
public enum PaymentMethodType
{
	None = 0,
	Cash = 1,
	CreditCard = 2
}
public class Customer 
{
	public int Id { get; set; }
	public string Name { get; set; }
	public string Description { get; set; }
	public PaymentMethodType PaymentMethod { get; set; }
}

Expected behavior
collection items with matching enum values should be returned

Can you test it with latest master?
I think, it could be duplicate of #1548.

@hopson-2 I tested your example with master and it works. It was recently fixed and will be present in the next incremental release.

Also, a tip: there's no need to run EnsureIndex over the id field, since the index over the id is always created upon the first insertion and it can't be dropped.

Hello, Thank you for the update and the tip.
