Mock client does not return value

Describe the bug A clear and concise description of what the bug is.

Hi, this is in the context of me adding qsharp-chemistry to conda-forge: https://github.com/conda-forge/staged-recipes/pull/18563

For building, I use QSHARP_PY_CLIENT=mock as the server is currently not available on conda-forge.

When importing qsharp.chemistry the import fails with

import: 'qsharp.chemistry'
Traceback (most recent call last):
  File "/home/conda/staged-recipes/build_artifacts/qsharp-chemistry_1649065353239/test_tmp/run_test.py", line 2, in <module>
    import qsharp.chemistry

    qsharp.packages.add("microsoft.quantum.chemistry.jupyter")

    logger.info("Loading complete: " + ';'.join(str(e) for e in pkgs))
TypeError: 'NoneType' object is not iterable

I believe this is because the mock server in qsharp-core does not correctly return the microsoft.quantum.chemistry.jupyter package.

To Reproduce Steps to reproduce the behavior:

1. Build package using QSHARP_PY_CLIENT=mock
2. Import package

Thanks for the report, let me take a look and see if I can get a fix together!

@cgranade Do you already have an idea what could cause this? I'm just sorta blocked on all of the other iq packages with this. :)

Hi @cgranade just wanted to ask if there are any updates here because it is still happening.
