Add `isTransactional` to `WallabagMigration` because PHP 8 behave differently with PDO transaction.
This is a workaround because we can't upgrade Doctrine Migration for now (upper versions have the fix).
- Build is now using Composer v2 (instead of v1)
- All actions have been updated to latest version
- Fix bug in PHP 8 were `$entry->getTags()` can't be properly used as a _traversable_ by `assertContains` during tests. Added a custom method `Entry::getTagsLabel()` which return a flatted tag array with only label
- Replace `assertNotRegExp` by `assertDoesNotMatchRegularExpression` because it was deprecated
Because:
PHP Fatal error: Class 'PHPUnit_Framework_BaseTestListener' not found in /home/travis/build/wallabag/wallabag/vendor/dama/doctrine-test-bundle/src/DAMA/DoctrineTestBundle/PHPUnit/LegacyPHPUnitListener.php on line 7
