Hybrid should skip properties with indexSearchable=False

[dirkkul]

How to reproduce this bug?

• have a property that is indexSearchable=False
• do a hybrid search without giving properties - might only happen with aggregate
• get error

weaviate.exceptions.WeaviateQueryError: Query call with protocol GQL Aggregate failed with message Error in GraphQL response: [
  {
    "locations": [
      {
        "column": 12,
        "line": 1
      }
    ],
    "message": "shard VHQYjfGOV5hV: sparse search: aggregate sparse search: bm25 objects: Searching by property 'product_id' requires inverted index. Is `indexSearchable` option of property 'prop' enabled? Set it to `true` or leave empty",
