Change CHAT API call GET /chat/search to better support the two main scenarios of: group-based chatting: supply txGroupId only private chatting: supply 2 'involving' addresses only Added some DB indexes to cater for above. GET /chat/search now returns specialized ChatMessage objects instead of ChatTransactions. This is to reduce unnecessary fetching of data from repository, and onward sending to API client.
