Version

What package version of the SDK are you using.

Describe the bug

I found that recently APP_ID empty check has been added in the SDK: 579888d#:~:text=not%20supported%22)-,if%20app_type%20%3D%3D%20%22userassignedmsi%22%3A,Exception(%22Property%20%27APP_ID%27%20is%20expected%20in%20configuration%20object%22),-app_tenantid%20%3D%20(.
However, tools like Bot Framework Emulator allow users to bypass APP_ID and APP_PASSWORD to emulate bot activities. Do we really need this check? Is it by design? If not, shall we remove it?

To Reproduce

Steps to reproduce the behavior:

1. Create a Python Teams bot
2. Use Bot Framework Emulator
3. See error

Expected behavior

Users can bypass APP_ID and APP_PASSWORD in the Python bot
