t3206: test_when_finished before dirtying operations, not after
Many existing tests in this script perform operation(s) and then use test_when_finished to define how to undo the effect of the operation(s). This is backwards. When your operation(s) fail before you manage to successfully call test_when_finished (remember, that these commands must be all &&-chained, so a failure of an earlier operation mean your test_when_finished may not be executed at all). You must establish how to clean up your mess with test_when_finished before you create the mess to be cleaned up. Also make sure that the body of test_when_finished deals with case where the cruft it wants to remove failed to be created, by using "rm -f" (instead of "rm") to remove potential cruft files, and having "|| :" after "git notes remove" to remove potential cruft notes---both of these by default fail when asked to remove something that does not exist, instead of being silently idempotent no-ops.
