[lockscreen] the password entry is not shared between screens

[Sebastien Bacher]

[Impact]

Using the Unity lockscreen on a multiple-screen session results in the password field being cleared every time different screen is focused.

[Test Case]

Using trusty candidate on a dual monitor config
- log into unity
- lock screen
- start typing your password on one screen
- move the pointer on the other screen

-> the entry is displayed empty

Ideally the same entry would be move so you can keep typing even if you happened to have move the focus, that's what lightdm/unity-greeter is doing

[Regression Potential]

Any modification to the password dialogs could result in the inability to unlock the screen or make passwords available in cleartext. Care has been take to avoind introducing such situations with this change.

[Other info]

The Ubuntu 14.04 LTS SRU fix has been cherry-picked from the Ubuntu 14.10 release, where it has been in production use for a few months.
