Neels Hofmeyr afe2ea5c4f bsc: show bug: do inter-BSC-out HO by measurement report
So far all handover tests trigger handover via VTY command. This means
that any bugs introduced in measurement report handling and handover
target selection are by definition not caught.

Almost a year ago, fixing a handover oscillation bug for intra-BSC
handover introduced a segfault for inter-BSC handover targets, because
for those the target.bts is NULL. Show this bug.
