Fix MmsSmsDatabaseHelper onUpgrade always destroying the database

Commit f589e3973167cf238f0997fc63ecc1e684d10527 mistakenly removed
the whole 67 version check step instead of just the upgrade steps,
so the upgrade ended up always falling through, wiping and recreating
the database.

Test: Build, observe database not being wiped on upgrade
