Incorrect indentation in try/rescue blocks.

[danieljaouen]

For example:

  defp compute_temperature(json) do
    try do
      temp = (json["main"]["temp"] - 273.15) |> Float.round(1)
      {:ok, temp}
      raise ArgumentError, message: "invalid argument foo"
    rescue
      error ->
        IO.puts "Error! in #{__MODULE__} #{inspect error}"
        :error
    end
  end

The final :error should have the same indentation as the IO.puts statement. However, elixir-mode indents it as follows:

  defp compute_temperature(json) do
    try do
      temp = (json["main"]["temp"] - 273.15) |> Float.round(1)
      {:ok, temp}
      raise ArgumentError, message: "invalid argument foo"
    rescue
      error ->
        IO.puts "Error! in #{__MODULE__} #{inspect error}"
      :error
    end
  end

Notice that the final :error is incorrectly indented.
