feat(server): load face entities faster (#5281)

The query executed when loading the "People" page joins, among others, over "personId".
The added indices improve the overall performance of those JOIN queries.

Additionally, one ORDER BY clause is dropped since the resulting values
will always be TRUE, and thus, sorting them does not change the result.
