impl/prod: Fix logging field output.

impl/prod: Fix logging field output.

By using the AppEngine context, logging calls would not have access to
logging fields that were set in subsequent contexts (most of them).
Retain both the AppEngine context (for logging calls) and the logger
context (for up-to-date logging configuration), and use the latter for
field extraction.
