Added folder to select statement & changed received to receivedTime

- Added folder to select statement for getInboxMessagesByAddress. When selecting messages for a specific address, only the messages within the *true* inbox should be returned. Currently there is an "inbox" table, but that table also has a folder column, with can contain a value of "inbox". Perhaps the folder column should be removed.

- Changed received to receivedTime. The time was not being returned properly.
