extensions/common/wasm coverage

[alyssawilk]

Hello, The Envoy project has recently started collecting per-extension coverage. You have been tagged with this issue as you are a co-owner of an extension, extensions/common/wasm, which is below the 96.6 percent coverage mark. Could you please take a look at coverage results (https://storage.googleapis.com/envoy-postsubmit/master/coverage/index.html) and add more tests when you get a chance? Once this is done you should be able to remove your extension from the exempt extensions in test/per_file_coverage.sh Thanks!

@alyssawilk please assign to me as well.

reopening because it's not yet regression-proof
