[sdk-scheme-adapter][bulk implementation] Fix stalling unit tests in CI.

[kleyow]

Summary: In the CircleCi pipeline, unit tests get stalled when running the test-unit job. It is the belief that this is caused by resources in one of the modules that aren't letting go of its resources and is stalling other modules from running.

There is a current workaround implemented in package.json. It seems --detectOpenHandles somehow prevents the issue in CI.

Here is a example ci failure https://app.circleci.com/pipelines/github/mojaloop/sdk-scheme-adapter/2327/workflows/71523b5d-5823-4afb-bd83-27a3b5dd8d60/jobs/16063

Severity: Low

Priority: Low

Expected Behavior Unit tests pass in CI in less than 5 minutes.

Steps to Reproduce

1. Create a branch copy of mvp/bulk-sdk
2. Remove --detectOpenHandles from test:unit in package.json
3. Push your branch and wait on circleci
