Improve logging and handling messages with missing timestamp

[clehner]

This prevents the following error:

Error: could not find matching timestamp for index:{"sync":true}
    at /home/cel/src/streamview-links/index.js:163:31
    at /home/cel/src/ssb-query/index.js:68:26
  Error: missing timestamp:undefined

I also removed the query logging which produces a lot of console output

ah, thanks. I think sync: false is right,
but if(ts) return cb(null, {}) is wrong.
you shouldn't need that line because
https://github.com/dominictarr/streamview-links/blob/master/index.js#L162
will bypass the lookup (and just let the {sync: true} value pass).

I see. I didn't have up-to-date streamview-links. After updating and removing that line, everything works. I'm not sure if sync: false is necessary now in createLogStream (e7e3830), but it shouldn't hurt. Rebasing now.

thanks, merged into 0.1.1 also now at
