Cleaned up upgrade steps for versions older than JB

Removed all upgrade steps from before jellybean. On any older version of
android, the database will upgrade to the current version by simply
dropping all the tables and calling onCreate.

Test: Manually tested by upgrading a version 621 database taken from an
old ics device to the current version 1200 and comparing the schema with
a fresh 1200 version database. Both schemas match.
