Splitting out the X11 display initialization from display_open() broke
restoring the previously active workspace in two ways:

 - when dynamic workspaces are used, the old workspaces haven't
   been restored yet, so we stay on the first workspace

 - when static workspaces are used, the code tries to access
   the compositor that hasn't been initialized yet, resulting
   in a segfault

Fix both those issues by splitting out restoring of the active workspace.
