Update refs for Rec!2006 (fix in seeding)

Reference updates for Rec!2006 (merged) Bug fix: if multiple Hough clusters are processed for the same X-Z track...

added testing label

@saiola please take a look at the diffs and check if everything is as expected.

Note that there was one failing test on both ref and mr builds: mc_cheated_pattern_recognition . If that also needs an update, we have to test again

@mstahl, looks fine, thanks!
