* Split activity table into sent and received parts (fixes #3103) The received activities are only stored in order to avoid processing the same incoming activity multiple times. For this purpose it is completely unnecessary to store the data. So we can split the table into sent_activity and received_activity parts, where only sent_activity table needs to store activity data. This should reduce storage use significantly. Also reduces activity storage duration to three months, we can reduce this further if necessary. Additionally the id columns of activity tables are removed because they are completely unused and risk overflowing (fixes #3560). * address review * move insert_received_activity() methods to verify handlers * remove unnecessary conflict line * clippy * use on conflict, add tests
