…t sample (#2240)

## Linked issues

closes: #2241 

## Details

Provide a list of your changes here. If you are fixing a bug, please
provide steps to reproduce the bug.
1. Fix bug that debugging in test tool is not working after local
debugging.
  a. Clone the sample.
  b. Select "Debug (Edge)" and press "F5".
  c. Stop debugging and Select "Debug in Test Tool".
  d. The Test Tool will show authentication error.
2. Fix the outdated lines in README file.

#### Change details

Environment variables like bot id and password will be read from
.localConfigs in npm script.
So the env file update in teamsapp.local.yml should be ".localConfigs".
Writing to ".env" file will pollute the Test Tool environment.
