Description of problem:
When you update main grid object list (like add|remote network), the left-pane tree is not refreshed, thus shows still old tree.

From TCMS case:
===============

* Setup

  Have working >= 3.4 setup. Have a refresh time (refresh icon inside web ui)
  set to 60 seconds. Be located in System tree (left pane)->DC->$dc->Networks,
  have the tree fully expanded.

* Action
  - Add new network dialog, click OK


* Expected Results

  - there's corresponding network event visible in bottom Events list, at this
  point of time (Feb 24 2014) the Event lists is updated every 5 secs
  (hardcoded).
  - the network is immediately added in main grid and also in the expanded tree.

Thus the main grid gets correctly updated but there does not occur any refresh for left-pane tree automatically.

Click left-pane's refresh button updates data but the tree gets semi-collapsed :/

Version-Release number of selected component (if applicable):
ovirt-engine-webadmin-portal-3.4.0-0.11.beta3.el6.noarch

How reproducible:
100%

Steps to Reproduce:
1. see above TCMS case
2.
3.

Actual results:
left-pane tree does not automatically refresh thus it does show old elements or does not show new elements

Expected results:
sync with other parts of web ui refresh
