/latest/run/{source}.zip URLs don't work for all sources

[arne-cl]

According to issue #706, the latest_run_processed_url URI template (http://results.openaddresses.io/latest/run/{source}.zip) should always
give me the latest version of that source file.

When testing sources from http://results.openaddresses.io/state.txt,
I found that a lot of them return a 404 error,
e.g. https://results.openaddresses.io/latest/run/ch/schwyz.zip .

(I stumbled upon this when trying to add custom sources to the pelias openaddresses importer pelias/openaddresses#425).

In this case, the source is set to skip=true which means the latest version is unavailable intentionally. Are others that you’re finding similar?

Here’s the full history of ch/schwyz: http://results.openaddresses.io/sources/ch/schwyz

Hi @migurski,

out of 300 files I checked (Europe plus surrounding countries), 46 returned an error.

From my perspective, it would be great if /latest/run would point to the latest successful run instead of the latest run.
