There may be multiple apk files with the same hash. Although it is not a
security issue to install one or the other (they are exactly the same
binary), they may have different metadata to display in the client.
Thus, it may result in weirdness if one has a different
name/description/summary etc).
This change takes each of the matching Apk objects from the database,
then asks them where they expect to be downloaded. It matches this
against the File that we are looking at and only returns if they match.
