chore(WISE-Client): Test wise-client-test flow

[hirokiterashima]

Description

We now have a wise-client-test container that runs the tests in WISE-Client and exposes port 9876 for debugging purposes. See this commit for changes.

This allows us to use the Debugger in VSCode to debug the tests in the WISE-Client project.

Test

1. Pull the latest from the WISE-Docker-Dev@develop
2. Follow the instructions on this wiki page and verify the following:

• starting the wise-client-test container runs the tests in WISE-Client
• you can debug the tests: add breakpoints and inspect state variables
