Fix redis not storing search in key

Fixes a bug where search key was not being stored as a redis key, due to manipulation of filters in _sanitize_event_keys() causing false positive results returned from arbitrary search filters

Example:

2024-05-11 14:09:36,949 - DEBUG - Fiters are: {'kinds': [31990], 'search': '7ab57c96fcb644c9d0d9ca0c93f40a863f7e8f6b33a4835b50ff3b3ac5c23129'}

2024-05-11 14:09:36,963 - DEBUG - Caching results , keys: {'kinds': [31990]}   value is : [[{"id": "a22aec54f45b1a33ebe2c7c545aa06aad9547f873810f933ed19d27ce489ad1f", "pubkey": "8b2ff7ceb4a1ea558bb929ce0d3513dfeca2cab712fd149551a961c822ace218", "kind": 31990, "created_at": 1706620119, "tags": [["d", "7ab57c96fcb644c9d0d9ca0c93f40a863f7e8f6b33a4835b50ff3b3ac5c23129"], ["k", "30402"], ["web", "https://shopstr.store/<bech-32>", "npub"]], "content": "", "sig": "aa0dffe7c09c0053ba1ca61c56e1955f04b75d28602120937f780e2c391e5529c1fc8bd048b4b9abe5dcc25f281a8c6740466b86f5cc5cbfcc0833a4ebe3db71"}]]

Creates copy of subscription_obj.filters (raw results for request_payload.get("event_dict", {}))
- Uses that as the redis key
Moved subscription_obj.base_query_builder into query branch (was creating query before checking for cached results)

Tested with multiple queries and search filters:
