    Blind fix tdf#108612 explicitly checking for and against clipboard document
    
     This is a combination of 2 commits.
    
    Attempt to blind fix tdf#108612 explicitly checking for clipboard document
    
    It seems that for some yet unknown reason in an (un)certain constellation
    ScDocument::IsClipboardSource() returns true because ScModule::GetClipDoc()
    does not return the clipboard document but the actual document instead, so
    destroying the clipboard document executes ScDocument::ClosingClipboardSource()
    and (or in earlier versions) ScDocument::ForgetNoteCaptions() on the actual
    document instead.
    
    Check also that ScDocument::bIsClip is set, hopefully curing the symptom, the
    real cause is something else.
    
    (cherry picked from commit d5020f35aec54f0241fa58557dc6caadc149f5a9)
    
    Another attempt to blind fix tdf#108612
    
    Oddly in that scenario on Windows there are two clipboard documents alive when
    destroying one, so the destroyed one erroneously is said to be a clipboard
    source and then detachs the comments' caption information.
    
    There's no legit case where a clipboard document could actually be the real
    original source of another clipboard document, so bail out if the caller
    already is one.
    
    (cherry picked from commit 52e09f2c03f7cc024b2973c4806283c324fc23df)
