caddytls: Set Issuer properly on automation policies (fix #3150) 

When using the default automation policy specifically, ap.Issuer would
be nil, so we'd end up overwriting the ap.magic.Issuer's default value
(after New()) with nil; this instead sets Issuer on the template before
New() is called, and no overwriting is done.
