Problems with restore

[fluxusfrequency]

exercism restore in the CLI doesn't update the following exercises correctly or at all:

-beer-song
-binary-search
-custom-set
-food-chain (outdated test file)
-house
-triangles (no test file?)

Thanks for the heads up, I'll dig into this. This problem is likely on the API side, either in exercism/x-api or in exercism/exercism.io.

OK, I figured it out. There are some submissions where the filename is listed as nil. I will create a data migration to fix this.
