Additional documentation for 1inch testing

[pmantica3]

Hello folks!

I have loved 1inch as a project. It's really simplified token trading for me. Testing it though has been a bit hard.

Per #15 there is no testnet support for 1inch. So the recommended mechanism for testing is to create a Ganache mainnet fork. I tried this approach and it didn't work so well. Every so often, I get like the following:

  Transaction: 0x9121fffc83795544412e56f3e376a31ca2787e469041e2967134556310afed4a

  Runtime error: revert
  Revert reason: callBytes failed: Error(LOP: bad signature)

I asked in discord what might be the cause of this error and someone responded saying that it seems that if there is a limit order in the route of the protocol then it won't work. However, there is no indication of how to turn off this routes.

So in general I would really appreciate:

1. Some guidance on how to turn off the limit orders
2. Some more general guidance on testing. I would love to know how the 1inch company tests the 1inch protocol.

Thanks again for the awesome work!
