The setup app doesn't load without loading the background app. Do you know why?

[sacomoto, 2015/09/30 17:40:53]

Ok, I found the issue. The background app registers an observer to launch the
paring_dialog:

Maybe remove this, and change the background.js not call |initEasyUnlock()|. We
can hide everything behind the BLE discovery flag
(userInfo[0].bleDiscoveryEnabled).

Okay, I removed this check.

Acknowledged.
