Golfed it all the way down to:
my $p = Promise.new;
$p.break("OH NOES");
await $p;
And fixed it, and added a test in S17-promise/basic.t. Seems it was a
regression when I improved error reporting for Promises a while ago to present
the backtraces of both the original error and the one where the result of the
Promise was acquired. To do that I used rethrow, but that got upset and spewed
an internal error (the one seen here) if given an exception that was never
previously thrown. Now it just copes.
