is_amp is broken

[gpsaggese]

Some tests are skipped and the reason seems to be

  File "/app/helpers/hgit.py", line 350, in _is_repo
    assert 0, (repo_full_name, repo_short_name)
           ^
AssertionError: ('causify-ai/helpers', 'helpers')

We should re-think a bit all this mechanism about identifying repos after all the latest changes.
