dynode outputs command does not properly report multiple Dynodes per TXID

[LordDarkHelmet]

Describe the issue

The dynode outputs command does not properly register all dynode outputs. If multiple dynodes are created using the send many command then the dynode outputs command will only report one of the capable Dynodes

Steps to reproduce

1. Use the send many command to make multiple Dynodes, for example send 1000 DYN to 10 unique virgin addresses.
2. Run the dynode outputs command and you will see only one Dynode.

Expected behavior (tell us what should happen)

Each capable Dynode should be shown. They will all have the same TXID, but each should have a unique output index.

Actual behavior (tell us what happens instead)

Only one Dynode is displayed.
From the testnet, where I created 10 Dynodes using a single transaction this is what I got when I ran dynode outputs

{
  "7a483f92900857ae471ae9995c63ddcadb06969ccba4bf03929f377347af1f4b": "9"
}

I was able to start all 10 dynodes by using the same TXID with each Dynode using output index 0 to 9. This just seems to be a reporting issue.

What platform are you using (Linux, Windows, Mac)

Tested using the Windows QT wallet v2.4.4.1
