0.4.4

Added Predicate.empty() method.

Returns a new, non-nil, NSPredicate object that will match every single row in the database.

This is especially helpful with:

1. The @FetchRequest property wrapper.
   • Using a nil predicate can cause unexpected behavior if you dynamically assign or edit the predicate at runtime.
2. Other Core Data quirks around nil predicates and updating when you do fancy stuff.

Before:

@FetchRequest(sortDescriptors: [], predicate: nil)

After

@FetchRequest(sortDescriptors: [], predicate: Predicate.empty())
