Handle invalidation of currently processed archives correctly

[sgiehl]

Description:

When a period is being invalidated for whatever reason, we currently update all existing archives to the state INVALIDATED. Invalidated archives may still be used for reporting until new archives were built.

Updating archives to invalidated currently is also done for archives that are still in progress. In progress archives aren't considered for the reporting. So updating them to invalidated while they are still processed currently has the effect, that unfinished archives might be used for reporting, causing report data to disappear, for reports that were not yet processed for this archive. Once the archiving is finished those archives are updated to OK, causing them to get final again, even if they had been marked as invalidated in between.

This PR fixes the behavior by introducing a new state to mark in progress archives invalidated. This new state won't be considered for reporting, but when the archiving finished, the status will be updated to INVALIDATED instead of OK.

The code changes make sense to me. I've left some minor code suggestions but it'd be ok if not accepted, too.
