mix local.rebar

[ghenry]

Note for others, I had to do:

mix local.rebar as erroring on mix setup:

10:42:25.692 [notice] Application eex exited: :stopped
==> phoenix_live_dashboard
could not compile dependency :phoenix_live_dashboard, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile phoenix_live_dashboard", update it with "mix deps.update phoenix_live_dashboard" or clean it with "mix deps.clean phoenix_live_dashboard"
** (MatchError) no match of right hand side value: {:error, {:telemetry, {'no such file or directory', 'telemetry.app'}}}

I also did this first:

mix deps.update phoenix_live_dashboard

Thanks for publishing this demo!
