Fixes the merge issue that's been done.

Somehow the merge from wip/h3nk3-1-ws-jim into wip/h3nk3-1-ws did not pick up the latest changes done so there was a mismatch between in what class ```InspectRequest``` is implemented. My bad for not running all tests (again) before merging with master.

It has been fixed in this PR + changed to preferred way of parsing JSON in the ```InspectRequest``` companion object. 

Also some import cleanups done in ```WebSocketActor```.
