Well, there is also a bit more simple solution to this. The actual problem is in using ABPeoplePickerNavigationController as a singleton object, setting its delegate to a view controller and then dismissing the view controller. So, in my case the solution that worked is this one:

- (void)peoplePickerNavigationControllerDidCancel:
(ABPeoplePickerNavigationController *)peoplePicker
{
    peoplePicker.peoplePickerDelegate = nil; // clear delegate prior to dismissing self
    [self.navigationController dismissViewControllerAnimated:YES completion:nil];
}

- (BOOL)peoplePickerNavigationController:
(ABPeoplePickerNavigationController *)peoplePicker
      shouldContinueAfterSelectingPerson:(ABRecordRef)person
                                property:(ABPropertyID)property
                              identifier:(ABMultiValueIdentifier)identifier
{
    [self displayPerson:person];
    peoplePicker.peoplePickerDelegate = nil; // clear delegate prior to dismissing self
    [self.navigationController dismissViewControllerAnimated:YES completion:nil];
    return NO;
}
