problems

1. There are currently no tests, testing the several Visual import stuff.
   What should be done: ensure that specific input (PDF / HTML / URL / XML + XSLT) produces the wanted output.
2. Currently the tests are not runnable when Visual Plugin is activated. The reason is, that Visual adds a field reviewFileId to the segment output. In all our test compare data this field is missing, so all tests comparing segment results against JSON segment results will fail. Either the field must be added or it must be removed since it is untestable content (there is already a method doing such stuff)
