Description of problem:
When a user changes the zone of an appliance from the appliance's own web UI, it will update the zone but fails to update the UI to reflect the change in the accordion tree on the page for configure>configuration>settings>zones. The Basic Information form on the configure page shows the correct zone in the dropdown selection field. 

Version-Release number of selected component (if applicable):
5.4.0.2.20150519003830_673f996

How reproducible:
always

Steps to Reproduce:
Two appliances should be set up: 
A1 - internal DB
A2 - using DB on A1. 

1. On A1, navigate to configure>configuration. On the accordion tree to the left, select Settings>Zones
2. Under configuration, select "Add a New Zone", and create a new Zone. 
3. Select your current EVM under "Default Zone". In the basic information field, change the Zone to your newly created one, and then Save.

Actual results:
On the accordion tree to the left, the appliance stays under the default zone. The dropdown item displays the correct updated Zone but it is not reflected in the tree. If you log into the web UI from A2 and look at the configuration page, the tree is correct.

Expected results:
The accordion tree would display the updated zone change for A1.
