fix test has_calls

Tests on python 3.12 are failing with:

```
$ pytest -k 'test_generate_jwt_with_passphrase'
FAILED tests/test_connection.py::test_generate_jwt_with_passphrase[pass123] - AttributeError: 'has_calls' is not a valid assertion. Use a spec for the mock if 'has_calls' is meant to be an attribute.
FAILED tests/test_connection.py::test_generate_jwt_with_passphrase[] - AttributeError: 'has_calls' is not a valid assertion. Use a spec for the mock if 'has_calls' is meant to be an attribute.
```

This commit fixes has_calls usage by replacing it with assert_has_calls
