CI Failure: Session tracking test failing against mysql 8

[casperisfine]

Ref: #1092

This test currently fail on CI when ran against mysql 8.0:

  1) Mysql2::Client session_track returns multiple session track type values when available
     Failure/Error: expect(res).to eq(["________"])

       expected: ["________"]
            got: nil

       (compared using ==)
     # ./spec/mysql2/client_spec.rb:1084:in `block (3 levels) in <top (required)>'

I dug a bit and mysql_session_track_get_first(wrapper->client, NUM2INT(type), &data, &length) returns 1, but I have no idea why.

@insom any idea what might be wrong?

@tenderlove Can you remove the allow-failure: true for the passed CI cases you confirmed in https://github.com/brianmario/mysql2/blob/master/.github/workflows/build.yml ? Thanks.
