Re-add tests #12
Description
Fix internal tests. Most of them fail due to changes made in PR #10 due to the way saving hub/user data is now handled...
Write tests for all modules, all old tests were removed because they had stopped working with recent changes, once re-added they should be enforced and tests should be required for any new code when reasonable. Once tests are added PRs should be required to pass all tests and include tests for added code before being merged.
