Failure of the git push doesn't fail tests

From build 14:

# fatal: 'test-2' does not appear to be a git repository
# fatal: The remote end hung up unexpectedly

The test failed but was perceived as a success

The issue that made the test fail was fixed in #18, but still the test should be fixed to not succeed.

Can we try this again with the latest changes?
