wallet: call InsertTxCheckIfExists to add a relevant tx

Browse source 
Let the method `addRelevantTx` use `InsertTxCheckIfExists` to insert a relevant 
transaction. If the transaction has already been recorded, the method call 
`addRelevantTx` will return early and not proceed with duplicating work of 
checking every output and duplicating the tx notification to the notification 
server.
