Default demo accounts currently are not working

[krumware]

The fdemo and edemo users do not seem to work at the moment. I have contacted IB support and it was indicated that the accounts "are being updated, and it could be at a few business days until the update is completed".

This is not a problem with ib-gateway-docker, but with IB. Just wanted to raise the flag in case anyone is having trouble. Will try to update this if things are resolved.
