nbstripout: fix tests

Building of nbstripout has failed after the version was bumped to 0.3.1 because:
the test files were missing from the new release tarball. This adds tests by
using the release tarball from GitHub instead of PyPI.

However, these tests fail because of a bug in one test. Thus, a patch is used to
fix the tests.
