Reuse user accounts in AJAX test suites.

[peterwilsoncc]

Try speeding up the AJAX test suite by re-using roles between tests.

Looks to save about a minute on the full PHPUnit action (which is only about a second on each individual test suite).

Pull request overview

This PR updates the AJAX PHPUnit base test case to reduce repeated user creation by caching a user ID per role when switching roles via _setRole(), with the intent of speeding up AJAX test execution.

Changes:

• Add a _user_ids property to store user IDs created for specific roles.
• Update _setRole() to reuse a previously created user ID for the requested role instead of always creating a new user.

Bot was correct, time advantage was chance (probably due to lack of people around).

• The docblock is now slightly misleading: it refers to self::_setRole() (suggesting a static call) and it no longer accurately describes how the cache is populated (it’s filled in set_up_before_class()). It also lacks an @var tag, unlike other properties in this class.

	/**
	 * User IDs created by self::_setRole().
	 *
	 * This stores the user IDs of various roles to allow for reuse.

This is a nope. Creating the shared fixtures in the test suite slows things down rather than speeds thigns up.

A lot of accounts are created but evidently fewer than this PR creates.
