Apply minor changes to PurgeService

- Remove various imports / unused fields
- Make CacheDataSource call source for purging on DB
- Minor: SQLite - place creation of PreparedStatement outside of loop
- Make specific purge actions called from task package-private (clearer from the outside which methods can be called from the outside)
