Index: Errors when re-indexing libraries with archived photos

[lastzero]

While extensively testing the development preview, we observed the errors shown below when re-indexing an entire photo library.

As it turned out, this was because the index data for archived photos was updated by default some time ago (introduced to fulfill a feature request).

With these changes, the problem should be fixed. Please report any remaining issues so we can fix them in a timely manner.
