Pass arbitrary keyword args to load_test_app

Applications can be written with arbitrary keyword arguments
in `setup_app`. The test app builder should support this by
allowing arbitrary keyword args to be passed to `load_test_app`,
and pass those along to `load_app`.

Revert "Fix a Py3 compatability issue with WebTest > 1.3.1 < 2.0"

This reverts commit 9ce0a79866fc4aee0b0988b5b75ce2432c97d0ee.

This was originally an attempted workaround for:
https://github.com/Pylons/webtest/commit/38137ee4b4afb300ab1a8bbf13f66e1a8238b1b8#diff-f8658b710075968677d52c7d013ec098R240
but is an inappropriate fix (that causes a bug of its own).
