Rename getCacheKey method to resolve conflict

The old repo highideas/laravel-users-online has a trait with getCacheKey method, so there is a conflict after the last releases of spatie/laravel-permission showing: `Trait method getCacheKey has not been applied, because there are collisions with other trait methods on App\Models\User`
