[gparted] Return constant reference from OperationDetail::get_description() (!94)

    Return constant reference from OperationDetail::get_description() (!94)
    
    All uses of get_description() copy construct to a local variable, not
    assign to a reference, so this doesn't save anything.  It is just being
    done to be consistent with making other getters return a constant
    reference.
    
    Closes !94 - Make more getter methods use return-by-constant-reference
