Remove idb describe querying

Summary: This can cause a lot of spam in the logs (locally, doesn't log as errors) and we've now found that `idb connect` is a better way to support remote devices. See https://docs.google.com/document/d/1Ih5eCyisMIzgKSJV6xichUBJMiioSJltcJCh6LCLecg/edit#bookmark=id.zhwvc6wk2bbz for more information.
