tests: fix failures due to environment LANG settings (Issue #286)

When the environment in which the tests are run dictates a non-English
language (e.g. via LANG=de_DE.UTF-8), certain tests started to fail because
formencode validation messages where translated in that language.

A test failing this way is for example
test_create_in_group_without_needed_permissions in
kallithea/tests/functional/test_admin_repos.py .

This is a regression of commit 3b29103657df (i18n: remove explicit
formencode language setting), but in fact reverting it is not the right
solution as there is no problem except during test execution.

Instead, force the formencode language to 'empty' (meaning English) for test
execution only.
