Prior to this fix, if a placement problem contains overlapping or duplicate-containing SameChipConstraints, the sequential placer (and thus all other placers built on it, e.g. hilbert and breadth_first) would fall over.
Though these smell of 'edge-case' they are actually very common in PyNN SpiNNaker's netlists... The generic placer test suite has been updated with a test case which include these behaviours..
