Hallo Mitchell!
Yes, it seems to be a bug here.

if(!gpio_get(GPIOC, GPIO0)) {
        /* If pin grounded, disable the pin bank and return */
        gpio_set_mode(GPIOC, GPIO_MODE_INPUT, GPIO_CNF_INPUT_FLOAT, GPIO0);
        rcc_peripheral_disable_clock(&RCC_APB2ENR, RCC_APB2ENR_IOPCEN);
        return false;
}
means that the bootloader will not be started if there is a ground  
connector on ADC2.
And, if you corrected your code like you did and there is no connector on  
ADC2 the USB VBUS will never be checked and USB forse will not work.

I think, there should be something like this:
if(!gpio_get(GPIOC, GPIO0)) {
        /* If pin grounded, disable the pin bank and return */
        gpio_set_mode(GPIOC, GPIO_MODE_INPUT, GPIO_CNF_INPUT_FLOAT, GPIO0);
        rcc_peripheral_disable_clock(&RCC_APB2ENR, RCC_APB2ENR_IOPCEN);
        return true;
}
