Riak initialization logic faulty

[StabbyCutyou]

Currently, our code to init riak based on a list of servers is not correct.

It takes what one might assume is a comma-delimited string, and puts it into an array. But that doesn't actually turn the string into a proper array, it just makes element 0 the same thing as the comma-ed string.

We should fix that to properly turn it into an array, or change the intention of the code.
