Bug: TrimList keeps oldest list entries instead of newest

Problem

The number of batches that are listed in the hangfire dashboard is limited by the maxListEntries setting that can be passed to UseBatches

config.AddHangfire(config =>
{
   // ...
   config.UseBatches(expirationTime: TimeSpan.FromDays(1), maxListEntries: 100, filterProvider: JobFilterProviders.Providers);
}

The TrimList method in PostgreSqlWriteOnlyTransaction is used to reduce the number of batch entries in the hangfire.list table to this limit. The current implementation is using a query where we order by id. It should be the ORDER BY ""id"" DESC otherwise we will always keep the oldest n batch entries instead of the newest.
