[BUGFIX] Only show workspace next/prev stage buttons with access

The buttons in the info dialog of a record in the workspaces
module shows the buttons "Publish to live" (or send to next
stage) now only shows the buttons if the editor has access to it,
same with sending an element back to the previous stage.
