ToDo:

• Implement tests for thechat event
• Fix the runTestClient and runGameTestClient gradle tasks
  • The runTestClient task is used to build the test structures, so it needs to have the property advancedperipheralstest.tags set to common,client so that both server and client tests can be built and executed.
  • The runGameTestClient is used to automatically run client tests, so the property advancedperipheralstest.tags needs to set to client so we only run the client tests, not the server tests.
  • With the current implementation this does not work correcly and both server and client tests are run on the client
