Override scope_for_create in Rails 6.1.3+

In rails/rails#41319 the `scope_for_create` method was changed so that
it called `where_clause.to_h` directly and now bypasses the patched
version of `where_values_hash`. This means we now have to override
`scope_for_create` in Rails 6.1.3 and later.

Fixes globalize#776
