As in the description of the sd_app_evt_wait() function says, the function will wait for application event. If you don't have application event, you will stay in that function. This explain why you can't get to nrf_drv_wdt_channel_feed(). And why you get there when you connect to a peripheral.

Our suggestion is either using a timer to do wdt feeding, or you replace sd_app_evt_wait() with

__WFE();
__SEV(); 
__WFE();

This way you will wake up when there is any BLE event (when softdevice is active), not just application event.
