Subject: Details in tests
- Added a test for calling 'debug.traceback' after yields inside
hooks. (Lua 5.3 seems to have a bug there.)
- Removed test "repeat test with '__open' metamethod instead of a
function", as the previous test already uses the '__open' metamethod.
(It changed when functions were removed as possible to-be-closed
variables).
