Update To Latest ExrethinkDB driver

[Linicks]

After trying to use this code against a non localhost server, it seems as though a chicken and the egg scenario is created. When I try to run this code with the older driver version I get an error after I change the following line of code in the repo.ex:

conn = Exrethinkdb.local_connection

• To-
  conn = Exrethinkdb.connect([host: '10.0.1.30', port: 28015])

Error:
** (Mix) Could not start application phoenix_exrethinkdb_chat: PhoenixExrethinkdbChat.start(:normal, []) returned an error: shutdown: failed to start child: PhoenixExrethinkdbChat.Repo
** (EXIT) an exception was raised:
** (UndefinedFunctionError) undefined function: Exrethinkdb.connect/1
Exrethinkdb.connect([host: '10.0.1.30', port: 28015])

If I update to the latest version of ExrethinkDB so that I can connect to a non localhost server, I get this error:
