entriesNewerThanSeqNum pagination fails with parsing SeqNum

[adzialocha]

This request (against aquadoggo with empty database):

{
  entriesNewerThanSeqNum(logId: "1", seqNum: "0", publicKey: "2f8e50c2ede6d936ecc3144187ff1c273808185cfbc5ff3d3748d1ff7353fc96") {
    edges {
      node {
        entry
      }
    }
  }
}

Leads to the following error:

[2022-07-08T16:41:26Z WARN  aquadoggo::replication::service] Replication request to peer https://362b-89-204-137-157.eu.ngrok.io/graphql failed: Replication query failed with error
    GQLClient Error: Look at json field for more details
    Message: Failed to parse "SeqNum": invalid type: integer `1`, expected a string

Sequence numbers can not be zero, so I guess the seqNum parameter needs to be 1 at least, but then we need to change how we paginate.
