Fix handling of blank moduleSetTag

Handling of blank moduleSetTag is very inconsistent.
Sometimes it will be returned as null, '' or 'not-specified'.
Specifically in the case of MODULE_UPGRADE_FAILED, on the retry,
a blank moduleSetTag will be returned as 'not-specified', leading
to incorrect upgrade.
