Fixes #517. The problem was that again, only the `vercode`s of apks were being compared to see if they were the same, rather than `vercode` and `id`. The result is that some new apks will incorrectly be asked to execute an `UPDATE` query rather than an `INSERT`. As such, they don't end up in our database at all because the `UPDATE` will not run against any row at all.
