Propagate onError

[rogeriochaves]

I noticed that secret-stack initiates a multiserver server but passes null as the onError parameter:

secret-stack/core.js

Line 167 in 06305ad

server = ms.server(setupRPC, null, function () {

as a result sometimes I have this error logged on my app, and there is nothing I can do about it:

Error replicating with @d64Q93XzBhbr2JCLWkZgvzKwTHMvwFgRdtw4fHFlF5k=.ed25519:

should we add an onError callback or is there a better way to capture those that I'm not aware of?

I think that error should be pretty harmless. As for the error handling part, I'm not sure what the best way would be to add it, given how the function is used in the file.
