Code review comment for lp:~maxiberta/launchpad/snap-name-extraction

Thanks Maxi,

We have discussed alternatives for the mock/call-counting strategy for testing the fact we are using yaml.safe_load(). Turns out that actually checking a malicious yaml content can't cause any harm was too involving for this test. So I am happy with the current state.

We also mentioned that, theoretically, we should be able to warn users in the form about repositories missing sufficient (only name for now) "snapcraft.yaml" content and prevent future errors. However, what we have right now is more friendly to initial setups (empty repo, for instance)
