Remove dependency on pytest for running tests (#2055)

Browse Source 
* Switch to plain unittest for skipping slow tests.

Add a RUN_SLOW environment variable for running them.

* Switch to plain unittest for PyTorch dependency.

* Switch to plain unittest for TensorFlow dependency.

* Avoid leaking open files in the test suite.

This prevents spurious warnings when running tests.

* Fix unicode warning on Python 2 when running tests.

The warning was:

    UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal

* Support running PyTorch tests on a GPU.

Reverts 27e015bd.

* Tests no longer require pytest.

* Make tests pass on cuda

An extensive test suite is included to test the library behavior and several examples. Library tests can be found in the [tests folder](https://github.com/huggingface/transformers/tree/master/transformers/tests) and examples tests in the [examples folder](https://github.com/huggingface/transformers/tree/master/examples).
Tests can be run using `pytest` (install pytest if needed with `pip install pytest`).
Tests can be run using `unittest` or `pytest` (install pytest if needed with `pip install pytest`).
Run all the tests from the root of the cloned repository with the commands:
```bash
python -m unittest discover -s transformers/tests -p "*test.py" -t .
python -m unittest discover -s examples -p "*test.py" -t examples
```
or
``` bash
python -m pytest -sv ./transformers/tests/
python -m pytest -sv ./examples/
```
By default, slow tests are skipped. Set the `RUN_SLOW` environment variable to `yes` to run them.
## OpenAI GPT original tokenization workflow
If you want to reproduce the original tokenization process of the `OpenAI GPT` paper, you will need to install `ftfy` (use version 4.4.3 if you are using Python 2) and `SpaCy`:
