With the rename of the stacktrace field to common_stacktrace, update the selftests to reflect this change. Copy the current selftest to test the backward compatibility "stacktrace" keyword. Also the "requires" of that test was incorrect, so it would never actually ran before. That is fixed now.

Looks good to me.
