* Make createLocalViewFactory compatible with Laravel 8
Fixes https://github.com/barryvdh/laravel-ide-helper/issues/1024
* tests: move up mockFilesystem so it get be re-used in other tests
Note: removed `$this->mockOutput = '';` as it was a no-op, that property
doesn't exist (it was probably a typo, but I guess we don't need it
anyway)
* tests: show basic features for ide-helper:meta working
* phpcs: enable also for config, resources and tests
* composer fix-style
* vendor/bin/phpunit -d --update-snapshots
* gha: instead of checking the style, fix and auto-commit it 💪
* tests: add abstract class for all database related tests
* tests: add abstract class for all ModelsCommand related tests
* tests: add GenerateBasicPhpdoc test
* tests: add CustomDate test
* tests: remove MITM abstract TestCaseDatabase, not useful here
* tests: skip new ModelsCommand test on Laravel < 6
* tests: remove CarbonImmutable checked
Since we decided to skip for Laravel < 6.0 anyway, it's always present
