Registry creation in ENS module throws an exception

[kelsos]

All issues which aren't created with this template will get immediately closed.

It seems like EnsModuleFactory createENS method never passes the instance of contractModuleFactory to the constructor of Ens resulting in contractModuleFactory being undefined when createRegistry is called.

https://github.com/ethereum/web3.js/blob/2f0ada25b3988e67ec0d9a86a593146a57b43114/packages/web3-eth-ens/src/factories/EnsModuleFactory.js#L47

Expected behavior

Call getAddress to get the address of a register name on ens.

Actual behavior

Calling getAddress throws the following exception.

Steps to reproduce the behavior

1. Setup web3 with the http provider (the rpc provider is a geth client on rinkeby)
2. Get the ens module web3.eth.ens
3. ens.getAddress()
