Schleuder::Filters specs shouldn't require files by path
Currently, the specs read:
# make sure we have the filters loaded, as they will be loaded lazily within the code Dir[File.join(File.dirname(__FILE__),'../../../lib/schleuder/filters/*/*.rb')].each do |file| require file end
This makes the test suite order dependent, as the Debian CI shows. Besides this, requiring files by path is expected to fail during Debians autopkgtest, as relative paths don't work then.
