Description

ClientConnectionTest.TestFailover is flaky:

Expected: instance of <System.Exception>
  But was:  null
   at Apache.Ignite.Core.Tests.Client.ClientConnectionTest.TestFailover() in /opt/buildagent/work/7bc1c54bc719b67c/modules/platforms/dotnet/Apache.Ignite.Core.Tests/Client/ClientConnectionTest.cs:line 618

The reason is that sometimes the client detects connection failure in the background with OnAffinityTopologyVersionChange callback.
