celery: drop config settings not supported in Celery 4

CELERY_SEND_TASK_ERROR_EMAILS has been removed, according to
https://docs.celeryproject.org/en/3.0/whatsnew-4.0.html#features-removed-for-simplicity :
"Tasks no longer sends error emails. This also removes support for
app.mail_admins, and any functionality related to sending emails."

The "ADMINS" prefix might be a left-over from the long removed
celery.conf.ADMINS - last seen on
https://docs.celeryproject.org/en/2.1-archived/reference/celery.conf.html#celery.conf.ADMINS .

The "ROUTES" prefix might refer to "CELERY_ROUTES" ... but it doesn't take a
simple string list anyway, so there is no point in treating it as a list value.

===================
Debugging Kallithea
===================

If you encounter problems with Kallithea, here are some instructions
on how to debug them.

.. note:: First make sure you're using the latest version available.


Enable detailed debug
---------------------

Kallithea uses the standard Python ``logging`` module to log its output.
By default only loggers with ``INFO`` level are displayed. To enable full output
change ``level = DEBUG`` for all logging handlers in the currently used .ini file.
This change will allow you to see much more detailed output in the log file or
console. This generally helps a lot to track issues.


Enable interactive debug mode
-----------------------------

To enable interactive debug mode simply comment out ``set debug = false`` in
the .ini file. This will trigger an interactive debugger each time
there is an error in the browser, or send a http link if an error occurred in the backend. This
is a great tool for fast debugging as you get a handy Python console right
in the web view.

.. warning:: NEVER ENABLE THIS ON PRODUCTION! The interactive console
             can be a serious security threat to your system.
