Make createLocalViewFactory compatible with Laravel 8 (#1026)

* 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
