ssb-ref bug

The ssb-ref@2.13.4 package is installed as a package under ssb-backlinks@0.7.3.

Consider the following few lines in ssb-ref/index.js:

   108      addr = addr.find(function (address) {
   109        return /^(net|wss?|onion)$/.test(address[0].name) && /^shs/.test(address[1].name)
   110      })

The function really ought to test if address is defined, and is an array of length >= 2. If address is undefined, as has just happened repeatedly here, sbot will crash:

~/.ssb/node_modules/ssb-backlinks/node_modules/ssb-ref/index.js:109
    return /^(net|wss?|onion)$/.test(address[0].name) && /^shs/.test(address[1].name)
                                                                                ^
