Fixed AbstractSingleNodeStreamDeploymentIntegrationTests

Fixes the ubuntu build issue. There was apparently some crosstalk with other AbstractSingleNodeStreamDeploymentIntegrationTests which set the testMessageBus in LocalSingleNodeStreamDeploymentIntegrationTests. The TMB is a wrapper to clean up transport resources gracefully and is expected to be null in the Local case. Running the build on Ubuntu exposed a bug where the local test was actually using a separate instance of RedisMessageBus to check the bindings.
