Fix join deprecation in php7.4

Fix join() passing glue after array deprecation, deprecated in php7.4

Thanks! @TheROPFather

Backpack V4 compatibility (fix)

Backpack v4 changed its master layout name, so this package wasn't working.

If you had this problem, publish views again with --force

php artisan vendor:publish --provider="EduardoArandaH\BackpackLogViewer\BackpackLogViewerServiceProvider" --force

Check compatibility with laravel 6

No issues found when migrating to laravel 6, just updating version.
