It is no longer possible to view graphs having no edge definitions
Fixed #941. Showing a collection did send a count request, as well as a fullCount for the query. fullCount in this case is superflous and has been removed. On the way fixed an issue with the number of documents not updating while filtering.
Added a test that the graph viewer is not loaded for graphs without edge definitions
