Sergey Biryukov bae6e1735b Tests: Ensure prerequisites are met for draft length tests in Tests_L10n.
These three tests for `wp_dashboard_recent_drafts()` would run into a PHP 8.1 "passing null to non-nullable" deprecation for the call to `ltrim()` when the result of `get_edit_post_link()` is passed to `esc_url()`.

Setting a deprecation expectation would not solve this as the returned value would still not match the expected value(s).

The recent drafts list is only displayed on the Dashboard screen for users with the `edit_posts` capability. By setting the current user to Editor, the prerequisites for `wp_dashboard_recent_drafts()` are met, which means the deprecation notice is avoided and the assertions will succeed.

This commit addresses a few errors in the test suite along the lines of:
{{{
1) Tests_L10n::test_length_of_draft_should_be_counted_by_words
ltrim(): Passing null to parameter #1 ($string) of type string is deprecated

The short version:

1. Create a clean MySQL database and user. DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.

2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.

3. $ svn up

4. Run the tests from the "trunk" directory:
   To execute a particular test:
      $ phpunit tests/phpunit/tests/test_case.php
   To execute all tests:
      $ phpunit

Notes:

Test cases live in the 'tests' subdirectory. All files in that directory will be included by default. Extend the WP_UnitTestCase class to ensure your test is run.

phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run. This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs. Pure unit tests may be used also, of course.

Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.

phpunit is intended to run at the command line, not via a web server.
