GET JournalTransaction improvement

[Stefan Hult]

We have problem with an integration when the number series are the same in JournalTransaction.

If we want to Get the AR transaction we can't use the:
 /controller/api/v2/journaltransaction/{journalTransactionNumber}
because that call gives us only the GL transaction. We have to use the:
/controller/api/v2/journaltransaction
and add it to a dictionary to find the AR transaction we are searching for.

I have two suggestions to change the API
1. Do the same as on SalesOrder (/journaltransaction/AR/100005) add the module name to the call.
2. Return all records with the same number, no matter what the module is.
