DEV: Add more debugging information to AR query logs on GitHub actions (#25237)

Why this change?

We have been chasing a problem with our flaky system test where the user
is logged out when it should never be.

What does this change do?

1. Logs the request path when lookup a user auth token.
2. Logs the request path and also the current thread's object id in
   ActiveRecord query logs.
