[Cashtab][Alias] Refactor Alias.js to use new alias-server endpoints

Summary:
T3216

This diff refactors Alias.js to connect to the new alias-server endpoints to check:

alias availability
aliases registered to the active wallet

These were not pushed as two separate diffs because they are dependent on each other e.g. once an alias is confirmed to be available and is then registered, the reviewer needs the 'aliases registered to address' component to be hooked up to alias-server at the same time to verify the registration on the Alias.js page.

Test Plan:

npm test
change alias flag in Ticker.js to true
npm start
navigate to the Alias screen and ensure existing registered aliases for this address are displayed
register a new alias that is available and ensure successful broadcast
wait for one confirmation and then refresh the page and verify registered alias is now displayed on Alias.js
verify registration status matches alias-server's alias endpoint
verify newly registered alias is recognized via alias-server's address endpoint
attempt to register an alias that is already confirmed and verify registration error
