[bug] clean up not always proper

[wzrdtales]

of state t not cleaned up properly

• t.i - might be ok still problematic
• t.c - might be ok, probably not
• t.f - problematic

t.f not cleaned up will cause phantom foreign keys after a rerun of a migration
t.i not cleaned up does not knowingly cause phantom keys yet, but might have a similar problem, will fix just as t.f

possibly fixed in 458c5e8 needs testing
