Updated move destination widget to hide closed dossiers.

Added review state condition "open" to query for destination of a move action.

We chose to use a hardcoded list, because there are currently no customized workflows so there will not be different states. Also the Tabbedview currently does it the same Way. 

In the tests we make a Catalog query ourselves because we only have the chance to use the render_tree function. But it would return the html so we would have to rely on Titles and normal ids which could exist multiple times.
