Current behavior

The following code:

case name_to_table(params["name"]) do
      nil ->
        send_resp(conn, :not_found, "")

      table ->
        ...
        dimensions =
          params_list(params, "dimensions", table.default_dimensions(), table.dimensions())
        ...
end

triggers the following warnings:

    warning: nil.default_dimensions/0 is undefined (module nil is not available or is yet to be defined)
    │
 27 │           params_list(params, "dimensions", table.default_dimensions(), table.dimensions())
    │                                                   ~

    │                                                                               ~
    │
    └─ lib/console_web/controllers/api/v1/report_controller.ex:27:79: ConsoleWeb.Api.V1.ReportController.show/2

Expected behavior

I expect no warnings since table cannot be nil.

Dup of #14058. It will be fixed on v1.19 but until then a tagged tuple should work!
