Fix for something i broke

[Niller2005]

somehow this happened:

/var/zenbot/extensions/exchanges/gdax/exchange.js:21
        throw new Error('please configure your GDAX credentials in conf.js')
        ^

Error: please configure your GDAX credentials in conf.js

    at Object.syncBalance (/var/zenbot/lib/engine.js:178:18)

    at runCallback (timers.js:781:20)
    at tryOnImmediate (timers.js:743:5)
    at processImmediate [as _immediateCallback] (timers.js:714:5)

but this fixes it :)
