App crashes if the calling application exits in between a Review request

[ajinkyaraj-23]

setup:
on nanos ledger device , run following test
python3 -m pytest test --device nanos --backend ledgercomm -k "test_benchmark" -s
When Review request pops up on ledger device, kill the pytest process.
Then if the app is built with debug mode, when you accpet or reject the request on the nanos device, the baking app crashes.with app error e=0x0005 LR = 0xC0DE52DA
if the app is built without DEBUG mode, when you accept or reject the app asks for PIN and exits.

2. When running benchmark, when the screen on nanos is blank, when the setup_app_context comes for second account, the review request screen does not come up.
