createEdge returns "database not found" error

[mikub]

Method createEdge takes graphName as a first argument - however this argument is in fact used as a databaseName during rest call URL construction.
see InternalEdgeDriverImpl line 54:

HttpResponseEntity response = httpManager.doPost(createEndpointUrl(graphName, "/_api/edge"), params, body);

However createEndpointUrl method takes following parameters:

protected String createEndpointUrl(String database, Object... paths) throws ArangoException

Property graphName is here used as a database name (first argument) in the createEndpointUrl method call and will be placed in the generated URL that should have this format:

http://server:port/_db/<database-name>/_api/edge

Currently following URL is generated:

http://server:port/_db/<graph-name>/_api/edge

which will always result in 404 and "database not found" error

I fixed the the function in 2.5.6-SNAPSHOT.
