Unicorn: set unicorn.ipWhitelist default to documented value
Re: #1499 (closed) - !887 (merged) documented the default was [ 0.0.0.0/0 ]
, however the default
was actually removed. This adds the default back.
Re: #1499 (closed) - !993 (merged) addressed a failure of slice
vs array
Relates to #1499 (closed)
