Title: Test to  show that the late_alert causes the rollup comms status to be set to warning when the extended instrument resource is retrieved

* Now the comms status roll up works.
* added assertion in integration test for the extended instrument's computed attribute to check that it works
* removed the DeviceCommsEvent from aggregate status computation code. Will remove more instances of DeviceCommsEvent soon.
