Sanity check failed due to message output

[icoris]

Hi,

I've been testing the fetcher on my program and I always get a Sanity check fail in fetch(). I've added additional debug messaging to show tokenIn and tokenOut, and this is returned:
2016/09/20 08:02:18 [overseer master] sanity check failed:d57f1402568b9d42, 2016/09/20 08:02:18 INFO:EcomRate.bdb-ConfigLoad - Retry - 5

It seems that the first message that is returned on stdOUT from my code is a database load INFO message, instead of the token. This is most likely occuring due to my import load order and my defined init.

For a quick fix I'm going to comment out the tokenIn/tokenOut check. But for a longer term fix I think Overseer needs to have a init function defined that outputs the token.

It needs to be documented though, before you print anything to stdout, at the top of main run overseer.SanityCheck().

I also encountered this problem and found the error by modifying the code debug.
So, you should remove the output before starting

Delete output before overseer.Run(overseer.Config !
