tests: get rid of yield-based tests

yield-based tests (tests that are actually generating tests) are a nose
feature which were also supported in pytest. However, since pytest-3.0 this
type of tests is deprecated, they will be removed in pytest-4.0.

The only yield tests present in the kallithea test suite are simply yielding
a method that does a single assert. The benefit of having each of these
asserts in a separate test is not very high.

Replace the yield by a direct call to the previously-yielded method. This
means the total test count reduces but the actual amount of test code is the
same.

===================
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.
