tests: revamp Face integrated tests

* Categorize tests into consumer, producer, IO routines.
* Split expressInterest tests.
* Add route toward null face when Interest timeout is expected.
* Merge similar setInterestFilter tests.
* Add test for oversized Data.
* Move InterestFilter-convert-to-Name test into unit tests.
