[BUG] Collection returns incorrect count when database loaded from memory stream

Version LiteDB commit 6d9ac6237ff8cae104a3c57a8de4ec55b4506e87 (June 15, 2022)

Describe the bug Collection returns incorrect count when database loaded from memory stream

Code to Reproduce

using LiteDB;
using System.Diagnostics;
using System.Text;

public static class Program
{
  public static void Main(string[] args)
  {
    const string DbName = "v5-test.db";

    var dbStr = File.ReadAllText(DbName);
    var strm = new MemoryStream(Encoding.ASCII.GetBytes(dbStr));
    using var db = new LiteDatabase(strm);

    // This works as expected
    //using var db = new LiteDatabase(DbName);

    var col1 = db.GetCollection("col1");
    var count = col1.Count();

    Debug.Assert(count == 3);
  }
}

v5-test.zip

Expected behavior Collection count should be 3 but is 0

I’m trying to get LiteDB working in WebAssembly: https://github.com/TrevorDArcyEvans/LiteDB.Studio.WebAssembly https://github.com/TrevorDArcyEvans/LiteDB.Studio.WebAssembly/blob/855818616ae29bfb3510dfc5f23ee15cc90b0784/Pages/Index.razor.cs#L100

var dataBytes = await file.ArrayBufferAsync();
var strm = GenerateStreamFromBytes(dataBytes);


private static Stream GenerateStreamFromBytes(byte[] bytes)
  {
    return new MemoryStream(bytes);
  }

//it work fine
private async Task OnDrop()
  {
      // var sql = $"DROP COLLECTION {_selColl};";
      // await UpdateQuery(sql);
      _db.DropCollection(_selColl);
      _collections = _db.GetCollectionNames().ToHashSet();
  }

Thanks for the guidance. It is now working as expected!
