Gap state is not updated when the advertising stop after the timeout

[pan-]

The state of the Gap is not properly updated when the advertising stop after a timeout.

Gap& gap = BLE::Instance().gap();

// advertising will last for 10 seconds
gap.setAdvertisingTimeout(10);
gap.startAdvertising();

Gap::GapState_t state = gap().getState(); // at this stage state.advertising is equal to true

// 11 seconds later advertising has stopped
Gap::GapState_t state = gap().getState(); // state.advertising is still equal to true
