Incomplete Schema

Problem/Motivation

Functional tests that use the events listing display result in the following error:

There was 1 error:
1) Drupal\Tests\recurring_events\Functional\ContextualLinkTest::testCustomContextualLink
Drupal\Core\Config\Schema\SchemaIncompleteException: Schema errors for views.view.recurring_events_event_instances with the following errors: views.view.recurring_events_event_instances:display.default.display_options.fields.date__value.settings.fromto missing schema, views.view.recurring_events_event_instances:display.events_listing.display_options.fields.date__value.settings.fromto missing schema

As far as I know, this is only causing problems with tests, but possibly there are other effects.

Steps to reproduce

Create a functional test that renders the event instance listing view provided by the recurring_events_views submodule, and run the test (I did so by pushing a MR with my new test). See example here: https://git.drupalcode.org/project/recurring_events/-/merge_requests/195...

Proposed resolution

Add any missing schemas or fix any incomplete ones.

Remaining tasks

• Maybe do a review of the schemas to check whether more are missing.
• Add any missing schemas or fix any incomplete ones.
