fix MI poll: don't mistake old published version as new version approved

The MI /devupload/dev/query API returns the currently-published app's status,
not the pending submission. appStatus=3 means the previous version is still
online, not that the new submission was accepted. Use updateVersion=true as
the approval signal; default updateVersion to false to avoid false positives.
