Remove 6 finally-block tests from SKIP_TEST_NAMES in generator.
The finally feature was already fully implemented in parser.sx and
compiler.sx — the tests were just being suppressed. Regenerating
the spec file makes them active.
Tests now passing:
- basic finally blocks work
- async basic finally blocks work
- finally blocks work when exception thrown in catch
- async finally blocks work when exception thrown in catch
- exceptions in finally block don't kill the event queue
- async exceptions in finally block don't kill the event queue
