Describe the bug
When running the python version of bernstein-vazirani.py on Quantum Cloud, with the env var set: NVQC_LOG_LEVEL=trace
It appears that the backend is reporting execution twice. Is this expected? The cpp version only reports execution once.
The test below is with 0.7.1, and uses the supplied bernstein_vazirani.py and cpp examples.
Steps to reproduce the bug
python bernstein_vazirani.py --target nvqc

Were we successful? True
Expected behavior
Executing the cpp example with --target nvqc and logging set to trace reports Execution Timing just one time, not twice.
Is this a regression? If it is, put the last known working version (or commit) here.
Not a regression
