If no shipping rates apply to the current order, no order summary should be displayed

Problem/Motivation

This is a follow-up issue to #3512001: Allow to modify the "There are no shipping rates available for this address." error message.

Currently, if no shipping rates apply to the current order and address given, and we estimate the tax rates and shipping methods, for the current order, the applying rate is simply omitted (as there isn't one).
But this shows an incorrect total summary, as there shouldn't be a total summary at all. Instead, something along the lines of "Could not calculate the total order summary" should be displayed.

(Note, that this case was also possible before #3512001: Allow to modify the "There are no shipping rates available for this address." error message).

A rate applies to the current order, and the "total_order_summary" gets adjusted correctly:

No rate applies to the current order. The "total_order_summary" still gets displayed even if no rate applies (ommiting the "Shipping Cost" ("Versandkosten") section entirely and therefore showing an incorrect total order summary, as none should be shown instead):

Steps to reproduce

Proposed resolution

If no rates apply, show a different template with a message along the lines of "Could not calculate the total order summary"
