Core v3: Some transactions don't return timestamp

[boldninja]

Expected Behavior

All transactions using API should return a timestamp.

Current Behavior

Some transactions when using api/wallets/<address>/transactions don't return timestamp in response.

Steps to Reproduce (for bugs)

Make a call to an address that has a few tx and some don't have timestamp api/wallets/<address>/transactions

Example below:

      {
         "id":"fdd6cbaaa5c23594fd70e0c7c5637ed4abbbda4f352726bddbd77a859f53a57f",
         "blockId":"4863696540053150556",
         "version":2,
         "type":0,
         "typeGroup":1,
         "amount":"200000000",
         "fee":"10000000",
         "sender":"AFyf2qVpX2JbpKcy29XbusedCpFDeYFX8Q",
         "senderPublicKey":"02f7acb179ddfddb2e220aa600921574646ac59fd3f1ae6255ada40b9a7fab75fd",
         "recipient":"AFyf2qVpX2JbpKcy29XbusedCpFDeYFX8Q",
         "signature":"210f5e03a5ca0f4fd839c8333c0ba9e917d41a0e3eccf79a8beac46b41dc7ec2740765dd57f420681e46e235d0f7e09a974764fc532767fe861746c4c9f2a7b2",
         "confirmations":0,
         "nonce":"3"
      },
