If changing the icon of a non-selected node, our refresh method doesn't work correctly.

[markadrake]

In our modified angular controller we have a refreshTree() method. This is intended to reload the node when an icon is set, or removed successfully.

This works as long as you are on the currently selected node. But when you are setting or removing the icon for a node that isn't currently selected / active, we don't get the reload and the old icon remains.
