Network app fails

[pablopi]

When you open the network app, you will see devices that dont exist on the DB.
It doesn't display the new devices found. Should be some kind of problems with the session.

Also, re-discovery button should need any effect or any feedback, you dont know if you had click it or not.
The bulb controller display have a strange behaviour, it cannot be clicked. @jsdario
