lei_mirror: fix circular reference

All of our $lei->workers_start callers can simply rely on
that wrapper to do the right thing and pass fields to
->wq_worker_start children, only.

This could manifest as a unbound memory growth if somebody is
constantly mirroring, and was causing tests to get stuck when
experimenting with a persistent lei-daemon for the entire
test suite.
