cabal replication bug

[rhodey]

A null reference error gets thrown from deep inside multifeed after cabal replication has been started with cabal.swarm(). Please see my proof-of-concept with steps to reproduce for more details.

/root/poc/node_modules/multifeed/mux.js:203
      feed.ready(function() { // wait for each feed to be ready before replicating.
           ^

TypeError: Cannot read property 'ready' of undefined

Thank you for reporting this @rhodey! 🌟

Looking into this revealed a bug in multifeed, which has been fixed. I've also bumped cabal-cli to 7.1.6, so upgrading that should pick up the patch. Thanks again!
