Elixir 1.4.0-rc.1 errors on startup about tzdata

[jschneider1207]

This is because of the following update to 1.4-rc.1

[GenServer] Log error on default handle_info/2 implementation

The Tzdata.ReleaseUpdater does not implement a handle_info, so the default (that now logs an error) is used.

Also, may be unrelated but I was having trouble starting the app up after doing this...

This is what would happen when I would start it:

=INFO REPORT==== 16-Dec-2016::11:30:40 ===
    application: logger
    exited: stopped
    type: temporary
** (Mix) Could not start application tzdata: exited in: Tzdata.App.start(:normal, [])

            (kernel) application_master.erl:273: :application_master.start_it_old/4

I fixed it by rm -rf _build deps and rebuilding the application.

I am getting the same error

Tzdata.ReleaseUpdater :tzdata_release_updater received unexpected message in handle_info/2: {#Reference<0.0.1.54193>,

  ref: #Reference<0.0.5.36545>}}

If #27 is merged, we will no longer need to implement handle_info. This is because if we remove the dependency on Task, handle_info will no longer get called. In the words of @sschneider1207

tasks send a message to the creating process when done
that await usually will consume
the Tzdata gen_server does not await the task

This is because of the following update to 1.4-rc.1

Sweet, I was wondering what changed. Thanks
