As an editor I want status of locked item gets updated immediately on other users/instances

Formerly feedback from Telia after Discovery Release review:
"7. Locked item not shown locked until refresh"

Current system behavior:

• After editor locking a node, the status, icon of node gets updated immediately on his/her working session, but not in the other users/instances session. The node is only got updated on the other users/sessions when the view/session gets refreshed, eg: close/then open parent node of locked-node, close/re-open the app/view

It is due to limitation of Vaadin, so this is not committed yet, will be investigated and planned later if any other workaround solution
