4. Make sure BT is off
5. Tap the phone with bluetooth headset

###Expected result:
The bluetooth turned on, the earphone paired and connected, and the device show on "Paired devices" area

###Actual result:
The bluetooth turned on, and the earphone paired and connected, but no device show on "Paired devices" area

Add some extra comments here:
Bluetooth headset get paired and connected. However, Bluetooth Settings seems cannot load paired devices. If the user does not do nfc pairing while in Bluetooth Settings page, this bug cannot hit.

This bug is related to timing issue.
While |onpairedstatuschanged|, paired status = true, Settings app queries immediately, but retrieve older value. After query completed, bluez return new property which indicates Paired == true.

1. Gaia app got onpairedstatuschanged
2. dbus event PropertyChanged
3. Gaia app queried the older paired status
4. property updated

Ah, this bug seems not easy to fix. Unless we did the following:
1. If we got dbus event PropertyChanged paired property from false to true, hold PropertyChange event.
2. Until we got device property change, and update to gaia, then we send PropertyChange event to gaia.

Since we're all migrate to kk based image. I don't see any reason to fix this for JB/ICS base. Reload Settings, this problem will be disappeared.
