Removed default value from $or variable on applyFilter function

[ch00n]

Leaving the $join variable blank when using PHP 8 causes an exception when running artisan.

An empty array has been assigned to the variable to prevent this from happening.

UPDATE: Related to this deprecated PHP feature: https://stackoverflow.com/a/65297280/518704

To ensure compatibility with PHP 8, the default value for $or has been removed.

I think the more correct way should be to remove $or default false
Passing The &$join must be passed as it's passed by reference. So no default value has sense here.

What concerns $or = false, it's ok to remove = false
