Why:
* Maintenance scripts in core are mostly untested
* Increasing this test coverage, especially for more critical
scripts, will help avoid bugs and regressions.
What:
* Add tests for renameUsersMatchingPattern.php
* Expand tests for renameUser.php
* Add TestSelectQueryBuilder::assertFieldValues, which is used
to assert against the result of ::fetchFieldValues.

Similiar to assertFieldValue(), but to assert one row.
Simpler as assertResultSet(), as it needs list with one array

* Add MediaWikiIntegrationTestCase::newSelectQueryBuilder(), which
creates a subclass of SelectQueryBuilder with assert methods.
* Migrate most callers of assertSelect() to this new query builder
interface.
