Subject: test: Always set ENTRY_POINT_DIR

pylint complains:

```
************* Module gitubuntu.integration_test
gitubuntu/integration_test.py:77:26: E0606: Possibly using variable 'ENTRY_POINT_DIR' before assignment (possibly-used-before-assignment)
```

So always set `ENTRY_POINT_DIR` even when this variable is not used when
`ENTRY_POINT_TYPE` is `None`.
