neighbor/udisks: add `this->` to work around GCC 6 bug

Since `this` was captured, it does not need to be specified, but GCC 6 can't do it. Since we want to support the standard compiler from Debian Stretch (stable), we need to work around this problem: src/neighbor/plugins/UdisksNeighborPlugin.cxx:239:12: error: cannot call member function 'void UdisksNeighborExplorer::Insert(UDisks2::Object&&)' without object Insert(std::move(o)); ~~~~~~^~~~~~~~~~~~~~ This fixes #300 which I previously thought was a different bug.
