Add 2 E2E tests to verify the 'debug' and 'launch' modes are correctly configured (#117)

Objective
Same as title.

Abstractions
Two test cases are added:

when 'Debug: Attach' is selected, we start in attach mode
when 'Debug: Launch' is selected, we start in launch mode
Also updated package.json to uninstall AutolispExt after E2E tests are done, by adding "-u" opition.

Tests performed
The new added tests work as expected.
