mockPeerChaincode not working

[diestrin]

First of all, thank you for this project, it has been really helpful to make the chaincode migrations from Go to TS <3

But I found a problem with mockPeerChaincode, trying to make a chaincode invoke another one. Looks like invokables is not being initialized anywhere, and also the invokeChaincode functions is calling the wrong function otherStub.MockInvoke and the correct one is otherStub.mockInvoke.

If I get some time in the near future I'll submit a PR with the fixes, just reporting these for now.

Thanks for reporting, this feature isn't included in the tests, so I'm not suprised it isn't working.
