Bug: Fusion Function on Hybrid ends up Relative Score even when using Ranked Fusion.

[pm390]

Currently when creating an Hybrid search and setting the Fusion Function this gets always set to Relative Score even when set to Ranked Fusion.

The root cause is a switch case with missing breaks that makes Ranked Fusion being overwritten by the Relative Score Function at Hybrid.java#L181-188.

    if (fusionType != null) {
      switch (fusionType) {
        case RANKED:
          hybrid.setFusionType(WeaviateProtoBaseSearch.Hybrid.FusionType.FUSION_TYPE_RANKED);
        case RELATIVE_SCORE:
          hybrid.setFusionType(WeaviateProtoBaseSearch.Hybrid.FusionType.FUSION_TYPE_RELATIVE_SCORE);
      }
    }
