[lockscreen] Re-focus password field after using media controls
requested to merge ngraham/plasma-workspace:re-focus-lock-screen--password-field-after-using-media-buttons into master
Because you're still going to want to unlock the screen eventually, and once that time comes, having keyboard focus still be on the media controls is going to be annoying because you'll start to type your password and nothing will happen.
