Fixed a bug during QuantumKernel refactor
Created by: tnguyen-ornl
I forgot to put the observable argument in the call.
Also, disable qpu_lambda
arg&&
forwarding since it doesn't work properly with by-value lambda function arguments (not captured). This is a regression that I introduced when trying to forward qpu_lambda arguments.
Hence, this will make using qpu_lambda
(non-copyable) as arguments illegal. Disable these tests for now.
