[Bug] BaseBearerTokenAuthenticationProvider.authenticate_request does not refresh token with authorization header is present

[michaeldcanady]

Describe the bug
When authentication a request the method authenticate_request fails to refresh an expired JWT token.

To Reproduce
Steps to reproduce the behavior:

1. preform any graph request requiring a token
2. verify request.headers has "authorization" key
3. wait until bearer token is expired
4. you will receive the following error "unable to parse claims from response" - upstream error due to having a bad token

Expected behavior
once expired authenticate_request should retrieve a new token.

Hey, @michaeldcanady , in our bug template, the first step was "1. Go to our off-the-shelf samples and pick one that is closest to your usage scenario. You should not need to modify the sample." Can you share what sample you actually use, rather than just providing your high level steps? Just looking into your steps, it sounds like your app did not even attempt token refresh between your step 3 & 4. But our off-the-shelf samples should have already taken care of that.

Hey @rayluo! I put this on the wrong repo by mistake, I migrated the issue to microsoft/kiota-python#237, where it's applicable!
