Small UI fix for widgets/app info shortcuts

- Switch order of widgets & more and app info.
- Start binding widgets after starting to update these shortcuts on the
  UI thread, so that they will show up without waiting for the bind
  logic, which can take a while. We already have a callback mechanism
  for enabling widgets & more after widgets are bound, so this was how
  it was supposed to work already.
