apiKey vs apikey

[FluxOtto]

key is documented as apiKey, but example and code uses apikey.

That it is not using the key is not immediately obvious because the API still works, except it doesn't return traffic information.

I actually found it when using the fork MMM-MyCommute by @jclarke0000, but that doesn't have an issues log.

Thanks for catching this! I fixed it my module, and I enabled the issues log.
