Summary

Adds tests for code of the core/users-query ability that no test runs, according to the Codecov report.

• The description, url, first_name, last_name, nickname and locale fields are returned with their values to a caller who can edit the user, and only description and url are returned to a caller who cannot.
• The execute callback honors an ID sent as a digit string, a float, a decimal string or a signed string, and rejects a fraction, a number below 1, a float beyond 2 ** 53, a negative digit string and a word.
• A row that is not a user is skipped when a query filter changes the fields of the query.
• A registration date that cannot be parsed is reported as null.

Testing

vendor/bin/phpunit --filter 'Tests_Abilities_API_WpRegisterCoreUsersAbility::'
vendor/bin/phpunit -c tests/phpunit/multisite.xml --filter 'Tests_Abilities_API_WpRegisterCoreUsersAbility::'
vendor/bin/phpcs tests/phpunit/tests/abilities-api/wpRegisterCoreUsersAbility.php

Mutation check: 12 changes to class-wp-abilities-users.php (each field, the integer parsing, the skip of rows that are not users and the date check) were each caught by a test.
