Creating an artifact with a duplicate name and location results in two artifacts

[Francis Ginther]

Calling the ticketartifact API twice with the same data appears to result in two artifacts being create, even though both have the same name and URL.

I ran into this while trying to add artifacts from the lander while it was stuck in an infinite loop. I soon had dozens of repeating copies of the same set of artifacts in the ticket view, but the container only had 5 real files.

here's an example of the call parameters (the file has been removed from storage):
[http://10.55.32.245:8080/api/v1/ticketartifact/]: {'ticket': '/api/v1/ticket/3/', 'type': 'RESULTS', 'name': 'lander_master.all.json', 'reference': 'https://swift.canonistack.canonical.com/v1/AUTH_a1412d7034ce49b2a980b84b15c04372/lander.3/lander_master.all.json'}

I'll file this as medium as the caller shouldn't normally be generating duplicate artifacts.

Francis - was this using my branch that added artifacts to the ticket-system? I was wondering if we shouldn't prefix some of these names from the lander with the jenkins buildnumber or something. That way we can see diffs between re-runs ?
