    loolwsd: avoid filtering out "duplicated" uno commands
    
    Problem since commit 8f48dabf28076fc448ff76ec5da1cdd59990c5b1 (loolwsd:
    discard requests that are in the queue already, 2015-07-21), e.g.
    "select-all, paste, select-all" doesn't have the same meaning as
    "select-all, paste".
    
    Quite possibly the condition should be inverted, and filtering out
    should be done only for a few commands, like "tile"; but at least
    filtering out "uno" is definitely problematic.
