webadmin: Prevent SystemTree from losing selection
There are basically two listeners for SystemTreeModel's
ItemsChanged event:
(1) SystemTreeModelProvider.updateDataProvider
- actual listener registration code is in
DataBoundTabModelProvider.onCommonModelChange
- this method selects root "System" node
(2) SystemTree.addModelListeners
- this method de-selects last selected node
Upon WebAdmin startup, (2) gets executed after (1) which
causes SystemTree to lose selection.
As a result, code calling SystemTreeModel.getSelectedItem
might blow up on NullPointerException.
This patch ensures SystemTree doesn't lose selection upon
SystemTreeModel's ItemsChanged event.
