Subject: [PATCH] Flip to `strict_exception_groups=False` in core tns

Since it'll likely need a bit of detailing to get the test suite running
identically with strict egs (exception groups), i've opted to just flip
the switch on a few core nursery scopes for now until as such a time
i can focus enough to port the matching internals.. Xp
