Subject: [PATCH] Fixed: constructing a 'RowCountChanged' notification
 generates a nil warning when dragging a row

Previously, when

- Dragging a row in the rule editor

would eventually try to generate a dictionary with key 'indexes' and a
nil value in the method __postRowCountChangedNotificationOfType:indexes:.
Generating an empty dictionary instead when there is no indexes solves
this issue.
