emizzle 349b2691c3 fix(@embark/ens): Handle cases when no “register” in config
## Issue 1 - “register” section missing
When the “register” section of `namesystem.json` was missing, ENS would not deploy the ENS contracts nor create the contracts’ artifacts.

### Fix 1
Fix ENS deployment routine to always deploy the ENS contracts. In the case of testnet/mainnet, the contracts’ addresses will be known and therefore will be understood as “already deployed” by the contract deployer.

## Issue 2 - “register” section exists for non-dev environment
Additionally, if a root domain was specified in the “register” section and the DApp connected to an external node where we do not own the ENS contracts (ie testnet), attempting to register a root domain would not be possible as we do not own the ENS contracts.

### Fix 2
Fix ENS deployment routine to check if we are on a network in which we own the ENS contracts. If we are not, and we have specified a “register” section, print a warning to the user that the  registration will be ignored. Additionally, remove the “register” section.
