adding reverse resolver fetch when graph fails to retreive ens name

[brossetti1]

GitHub Issue

#1731

Changes

• added a backup contract call to the reverse records to ensure that eth name is retrieved.

This solution works, I am not sure if it is the right solution though. I spent some time in the ens subgraph trying to grab this information but I was not able to. It turns out @scottrepreneur opened a pr for this on there subgraph a while ago

I can pick that subgraph pr up and we can attempt to fix it that way depending on what we want to do here

Packages Added

eth-ens-namehash - adding normalize check as recommended by ens docs

Details

you can see the call return the right address in this console log:

1. graph is called which returns null for the reverseRegistations (ie 0 length)
2. contract is called which correctly identifies the ens name (hardcoded griffs address in the actual console.log on my local environment)
