    tab: avoid double removal
    
    Some scenarios caused the page to be removed twice, putting us in
    undefined terrotory
    
    Rearrange things a little so that pages are always managed by …pages…
    rather than a tab trying to remove itself
    
    Use a vfunc rather than connecting to our own signal
