`.tsp._history`: drop `feed_is_live` syncing, another seg flag

The `await feed_is_live.wait()` is more or less pointless and would only
cause slower startup afaig (as-far-as-i-grok) so i'm masking it here.
This also removes the final `strict_exception_groups=False` use from the
non-tests code base, flipping to the `tractor.trionics` collapser once
and for all!
