use encodeURIComponent on JobId

[samishal1998]

I've been using / as a separator in the Job Ids, Since Bull is recommending to use any separator other than : because they themselves follow Redis conventions.

But When I setup bullboard I found that it doesn't work with the / because it's not encoded in the URL

Ok, will you make a PR to fix this?
