If a blank nodeID was previously passed in it resulted in a node list request. The response would then fail to umarshal into a `Node` type returning a JSON error. This adds an extra validation to all inspect calls to check that the ID that is required is provided and if not return an error. Signed-off-by: Emil Davtyan <emil2k@gmail.com>
