[apps/apps_container] Add timer to circuit breaker

Browse Source 
poincareCircuitBreaker requires the Back key to be pressed for at least
50 ms before interrupting a computation.
This is effectively invisible for the user, but fixes a bug in
Calculation :
  - When leaving the additional results for a result using units by
    pressing the Back key, a reduction preceding a call to removeUnits
    would be interrupted, causing an undefined behaviour.
