Invalid market don't throws error

[imtoori]

If I check a market using a wrong format the function getlastprice get a nil error, but it should throw an error with something like "market invalid".
An example: btcltc instead of ltcbtc throws no error

I think that actually no matter what invalid request you send - there's no error.

Looked at the code, it's actually not checking the result of the request - only that it returned.

Will try to fix the issue and send a PR.
