bug: password field is not focused on screen wake

[edfloreshz]

Sometimes after waking the screen I have to manually click on the password field to focus it. I haven't figured out a way to replicate this behavior.

I have noticed however, that you can click Tab you can focus either the buttons, the password field or nothing at all, I believe that the latter is capturing the focus and that's what causes the password field to be unfocused.

Steps to reproduce

1. Super + Esc to show the greeter.
2. Click on the password field if not focused.
3. Click Tab and see the focus disappear.

The focus should go to the buttons and back to the password field, there's something else capturing the focus.

I think this is a duplicate of #135?

Right, I'll close this and comment on #135
