No-op refactor to support more than 2 dbs in DatabaseHelper
Currently, the DatabaseHelper assumes MediaProvider can only have 2
dbs, so if a db is NOT internal, it is external. For the photo picker,
we will introduce a separate db, picker.db which breaks this
assumption.
In preparation to introduce the picker.db, we refactor the code with
explicit methods to check if db is internal or external. In future cl,
we'll add an explicit check for picker db.
