Load module types from referecced group for app_policies

If appllication have default policies, sqldb does not store module types for this application separately.

During loading db SDL should check that application have default policies
and select from module_types sql table sing  "default" key but not appid key.

In function `GatherApplicationPoliciesSection` already exist check for default policies :

```
    if (IsDefaultPolicy(app_id)) {
      (*policies).apps[app_id].set_to_string(kDefaultId);
    }
```

Its setup stringified representation of application policies : "default".

This stringified reference ("default") used for select module type.
