Stop button is still rendered after the workspace was stopped

[fioan89]

Steps to reproduce:

1. On a running workspace, press the Stop button either from the quick actions button or from the pop-up menu
2. wait for the workspace to stop.
3. Stop action button is still enabled while Start button is disabled.

Seems solved for me on #20

Although the Updates keep showing after I hit Update

Quitting and restarting Toolbox disables the Update action.

Weird, I can still reproduce it with the latest code. I'll investigate this. BTW it makes sense for the action buttons to have a correct state after Toolbox restart because they were freshly initialized with data from backend.
