Fixes candidate list showing nothing

What does this MR do and why?

Fixes candidate list showing nothing

Candidate list was being refreshed and items would disappear when changing tabs, since query variables were passed in a wrong way.

How to set up and validate locally

1. In rails console enable the feature flag

   Feature.enable(:model_registry)

2. Create a model and a bunch of candidates

   p = Project.find_by_id(1)
   m = Ml::FindOrCreateModelService.new(p, "model_1").execute
   50.times { |i| Ml::CreateCandidateService.new(m.default_experiment, {}).execute }

3. Navigate to <gdk>/<project>/-/ml/models and select the model, then select the Version candidates tab, switch to Version and back to Version candidates: data should still be displayed and navigation should work
