Subject: [PATCH] Delete leaf RegressionSM instances when they complete

ReRegressionSM::run() completes synchronously and never reaches
regression_sm_waiting(), so nothing ever freed the six instances the
test builds or the six clones RegressionSM::run() makes for the repeat
counts. Composite nodes already delete themselves; leaves now follow
the same contract CacheTestSM::complete() uses.

Coverity CID 1022149, CID 1022150, CID 1022151.
