Bug 20495: (follow-up) Correct search for report by name

Ultimately we should probably remove name access as it is not a unique
id, but this should preserve existing behaviour

To test:
Create a report
Use the service link to confirm the report runs
Replace id=# parameter with name=XXXXXX
Confirm URL works

Note: We should not remove the param "name", it's a feature, see bug 8256.
